# Summary of Regression Models as HTML Table

#### Daniel Lüdecke

#### 2025-07-10

`tab_model()` is the pendant to `plot_model()`, however, instead of creating plots, `tab_model()` creates HTML-tables that will be displayed either in your IDE’s viewer-pane, in a web browser or in a knitr-markdown-document (like this vignette).

HTML is the only output-format, you can’t (directly) create a LaTex or PDF output from `tab_model()` and related table-functions. However, it is possible to easily export the tables into Microsoft Word or Libre Office Writer.

This vignette shows how to create table from regression models with `tab_model()`. There’s a dedicated vignette that demonstrate how to change the table layout and appearance with CSS.

Note! Due to the custom CSS, the layout of the table inside a knitr-document differs from the output in the viewer-pane and web browser!

    # load package
    library(sjPlot)
    library(sjmisc)
    library(sjlabelled)

    # sample data
    data("efc")
    efc <- as_factor(efc, c161sex, c172code)

## A simple HTML table from regression results

First, we fit two linear models to demonstrate the `tab_model()`-function.

    m1 <- lm(barthtot ~ c160age + c12hour + c161sex + c172code, data = efc)
    m2 <- lm(neg_c_7 ~ c160age + c12hour + c161sex + e17age, data = efc)

The simplest way of producing the table output is by passing the fitted model as parameter. By default, estimates, confidence intervals (CI) and p-values (p) are reported. As summary, the numbers of observations as well as the R-squared values are shown.

    tab_model(m1)

| Total score BARTHEL INDEX

(Intercept) | 87.15 | 77.96 – 96.34 | <0.001

## Automatic labelling

As the sjPlot-packages features labelled data, the coefficients in the table are already labelled in this example. The name of the dependent variable(s) is used as main column header for each model. For non-labelled data, the coefficient names are shown.

    data(mtcars)
    m.mtcars <- lm(mpg ~ cyl + hp + wt, data = mtcars)
    tab_model(m.mtcars)

| mpg
--- | ---
Predictors | Estimates | CI | p
(Intercept) | 38.75 | 35.09 – 42.41 | <0.001
cyl | -0.94 | -2.07 – 0.19 | 0.098
hp | -0.02 | -0.04 – 0.01 | 0.140
wt | -3.17 | -4.68 – -1.65 | <0.001
Observations | 32
R2 / R2 adjusted | 0.843 / 0.826

If factors are involved and `auto.label = TRUE`, “pretty” parameters names are used (see `format_parameters()`.

    set.seed(2)
    dat <- data.frame(
      y = runif(100, 0, 100),
      drug = as.factor(sample(c("nonsense", "useful", "placebo"), 100, TRUE)),
      group = as.factor(sample(c("control", "treatment"), 100, TRUE))
    )

    pretty_names <- lm(y ~ drug * group, data = dat)
    tab_model(pretty_names)

| y
--- | ---
Predictors | Estimates | CI | p
(Intercept) | 66.84 | 52.97 – 80.71 | <0.001
drug [placebo] | -7.18 | -28.25 – 13.89 | 0.500
drug [useful] | -30.95 | -53.08 – -8.82 | 0.007
group [treatment] | -21.66 | -40.13 – -3.19 | 0.022
drug [placebo] × group [treatment] | 4.15 | -23.68 – 31.98 | 0.768

Observations | 100
R2 / R2 adjusted | 0.116 / 0.069

### Turn off automatic labelling

To turn off automatic labelling, use `auto.label = FALSE`, or provide an empty character vector for `pred.labels` and `dv.labels`.

    tab_model(m1, auto.label = FALSE)

| barthtot
--- | ---
Predictors | Estimates | CI | p
(Intercept) | 87.15 | 77.96 – 96.34 | <0.001
c160age | -0.21 | -0.35 – -0.07 | 0.004
c12hour | -0.28 | -0.32 – -0.24 | <0.001
c161sex2 | -0.39 | -4.49 – 3.71 | 0.850

c172code3 | -1.64 | -7.22 – 3.93 | 0.564
Observations | 821
R2 / R2 adjusted | 0.271 / 0.266

Same for models with non-labelled data and factors.

    tab_model(pretty_names, auto.label = FALSE)

Observations | 100
R2 / R2 adjusted | 0.116 / 0.069

## More than one model

`tab_model()` can print multiple models at once, which are then printed side-by-side. Identical coefficients are matched in a row.

    tab_model(m1, m2)

## Generalized linear models

For generalized linear models, the ouput is slightly adapted. Instead of Estimates, the column is named Odds Ratios, Incidence Rate Ratios etc., depending on the model. The coefficients are in this case automatically converted (exponentiated). Furthermore, pseudo R-squared statistics are shown in the summary.

    m3 <- glm(
      tot_sc_e ~ c160age + c12hour + c161sex + c172code,
      data = efc,
      family = poisson(link = "log")
    )

    efc$neg_c_7d <- ifelse(efc$neg_c_7 < median(efc$neg_c_7, na.rm = TRUE), 0, 1)
    m4 <- glm(
      neg_c_7d ~ c161sex + barthtot + c172code,
      data = efc,
      family = binomial(link = "logit")
    )

    tab_model(m3, m4)

| Services for elderly | neg c 7 d

### Untransformed estimates on the linear scale

To plot the estimates on the linear scale, use `transform = NULL`.

    tab_model(m3, m4, transform = NULL, auto.label = FALSE)

--- | --- | ---
Predictors | Log-Mean | CI | p | Log-Odds | CI | p

R2 Nagelkerke | 0.106 | 0.191

## More complex models

Other models, like hurdle- or zero-inflated models, also work with `tab_model()`. In this case, the zero inflation model is indicated in the table. Use `show.zeroinf = FALSE` to hide this part from the table.

    library(pscl)
    data("bioChemists")
    m5 <- zeroinfl(art ~ fem + mar + kid5 + ment | kid5 + phd + ment, data = bioChemists)

    tab_model(m5)

## Show or hide further columns

`tab_model()` has some argument that allow to show or hide specific columns from the output:

- `show.est` to show/hide the column with model estimates.
- `show.ci` to show/hide the column with confidence intervals.
- `show.se` to show/hide the column with standard errors.
- `show.std` to show/hide the column with standardized estimates (and their standard errors).
- `show.p` to show/hide the column with p-values.
- `show.stat` to show/hide the column with the coefficients’ test statistics.
- `show.df` for linear mixed models, when p-values are based on degrees of freedom with Kenward-Rogers approximation, these degrees of freedom are shown.

### Adding columns

In the following example, standard errors, standardized coefficients and test statistics are also shown.

    tab_model(m1, show.se = TRUE, show.std = TRUE, show.stat = TRUE)

| Total score BARTHEL INDEX
--- | ---
Predictors | Estimates | std. Error | std. Beta | standardized std. Error | CI | standardized CI | Statistic | p

carer’s level of education: high level of education | -1.64 | 2.84 | -0.06 | 0.10 | -7.22 – 3.93 | -0.24 – 0.13 | -0.58 | 0.564
Observations | 821
R2 / R2 adjusted | 0.271 / 0.266

### Removing columns

In the following example, default columns are removed.

    tab_model(m3, m4, show.ci = FALSE, show.p = FALSE, auto.label = FALSE)

| tot_sc_e | neg_c_7d
--- | --- | ---
Predictors | Incidence Rate Ratios | Odds Ratios
(Intercept) | 0.30 | 6.54
c160age | 1.01 |
c12hour | 1.00 |
c161sex2 | 1.01 | 1.87
c172code2 | 1.47 | 1.23
c172code3 | 1.90 | 1.37
barthtot |  | 0.97
Observations | 840 | 815
R2 Nagelkerke | 0.106 | 0.191

### Removing and sorting columns

Another way to remove columns, which also allows to reorder the columns, is the `col.order`-argument. This is a character vector, where each element indicates a column in the output. The value `"est"`, for instance, indicates the estimates, while `"std.est"` is the column for standardized estimates and so on.

By default, `col.order` contains all possible columns. All columns that should shown (see previous tables, for example using `show.se = TRUE` to show standard errors, or `show.st = TRUE` to show standardized estimates) are then printed by default. Colums that are excluded from `col.order` are not shown, no matter if the `show*`-arguments are `TRUE` or `FALSE`. So if `show.se = TRUE`, but`col.order` does not contain the element `"se"`, standard errors are not shown. On the other hand, if `show.est = FALSE`, but `col.order` does include the element `"est"`, the columns with estimates are not shown.

In summary, `col.order` can be used to exclude columns from the table and to change the order of colums.

    tab_model(
      m1, show.se = TRUE, show.std = TRUE, show.stat = TRUE,
      col.order = c("p", "stat", "est", "std.se", "se", "std.est")
    )

### Collapsing columns

With `collapse.ci` and `collapse.se`, the columns for confidence intervals and standard errors can be collapsed into one column together with the estimates. Sometimes this table layout is required.

    tab_model(m1, collapse.ci = TRUE)

## Defining own labels

There are different options to change the labels of the column headers or coefficients, e.g. with:

- `pred.labels` to change the names of the coefficients in the Predictors column. Note that the length of `pred.labels` must exactly match the amount of predictors in the Predictor column.
- `dv.labels` to change the names of the model columns, which are labelled with the variable labels / names from the dependent variables.
- Further more, there are various `string.*`-arguments, to change the name of column headings.

    tab_model(
      m1, m2,
      pred.labels = c("Intercept", "Age (Carer)", "Hours per Week", "Gender (Carer)",
                      "Education: middle (Carer)", "Education: high (Carer)",
                      "Age (Older Person)"),
      dv.labels = c("First Model", "M2"),
      string.pred = "Coeffcient",
      string.ci = "Conf. Int (95%)",
      string.p = "P-Value"
    )

## Including reference level of categorical predictors

By default, for categorical predictors, the variable names and the categories for regression coefficients are shown in the table output.

    library(glmmTMB)
    data("Salamanders")
    model <- glm(
      count ~ spp + Wtemp + mined + cover,
      family = poisson(),
      data = Salamanders
    )

    tab_model(model)

## Style of p-values

You can change the style of how p-values are displayed with the argument `p.style`. With `p.style = "stars"`, the p-values are indicated as `*` in the table.

    tab_model(m1, m2, p.style = "stars")

Another option would be scientific notation, using `p.style = "scientific"`, which also can be combined with `digits.p`.

    tab_model(m1, m2, p.style = "scientific", digits.p = 2)

### Automatic matching for named vectors

Another way to easily assign labels are named vectors. In this case, it doesn’t matter if `pred.labels` has more labels than coefficients in the model(s), or in which order the labels are passed to `tab_model()`. The only requirement is that the labels’ names equal the coefficients names as they appear in the `summary()`-output.

    # example, coefficients are "c161sex2" or "c172code3"
    summary(m1)
    #>
    #> Call:
    #> lm(formula = barthtot ~ c160age + c12hour + c161sex + c172code,
    #>     data = efc)
    #>
    #> Residuals:
    #>     Min      1Q  Median      3Q     Max

## Keep or remove coefficients from the table

Using the `terms`- or `rm.terms`-argument allows us to explicitly show or remove specific coefficients from the table output.

    tab_model(m1, terms = c("c160age", "c12hour"))

Predictors | Estimates | CI | p
carer’age | -0.21 | -0.35 – -0.07 | 0.004
average number of hours of care per week | -0.28 | -0.32 – -0.24 | <0.001
Observations | 821
R2 / R2 adjusted | 0.271 / 0.266

Note that the names of terms to keep or remove should match the coefficients names. For categorical predictors, one example would be:

    tab_model(m1, rm.terms = c("c172code2", "c161sex2"))
