This function takes a regression model object and returns a formatted table that is publication-ready. The function is highly customizable allowing the user to obtain a bespoke summary table of the regression model results. Review the tbl_regression vignette for detailed examples.

Regression model object


Not used


List of formulas specifying variables labels, e.g. list(age ~ "Age", stage ~ "Path T Stage")


Logical indicating whether to exponentiate the coefficient estimates. Default is FALSE.


Variables to include in output. Input may be a vector of quoted variable names, unquoted variable names, or tidyselect select helper functions. Default is everything().


By default categorical variables are printed on multiple rows. If a variable is dichotomous (e.g. Yes/No) and you wish to print the regression coefficient on a single row, include the variable name(s) here--quoted and unquoted variable name accepted.


Must be strictly greater than 0 and less than 1. Defaults to 0.95, which corresponds to a 95 percent confidence interval.


Logical argument indicating whether to include the intercept in the output. Default is FALSE


Function to round and format coefficient estimates. Default is style_sigfig when the coefficients are not transformed, and style_ratio when the coefficients have been exponentiated.


Function to round and format p-values. Default is style_pvalue. The function must have a numeric vector input (the numeric, exact p-value), and return a string that is the rounded/formatted p-value (e.g. pvalue_fun = function(x) style_pvalue(x, digits = 2) or equivalently, purrr::partial(style_pvalue, digits = 2)).


Option to specify a particular tidier function for the model. Default is to use broom::tidy, but if an error occurs then tidying of the model is attempted with parameters::model_parameters(), if installed.


add a reference value. Default is FALSE






A tbl_regression object


The default method for tbl_regression() model summary uses broom::tidy(x) to perform the initial tidying of the model object. There are, however, a few models that use modifications.

  • "parsnip/workflows": If the model was prepared using parsnip/workflows, the original model fit is extracted and the original x= argument is replaced with the model fit. This will typically go unnoticed; however,if you've provided a custom tidier in tidy_fun= the tidier will be applied to the model fit object and not the parsnip/workflows object.

  • "survreg": The scale parameter is removed, broom::tidy(x) %>% dplyr::filter(term != "Log(scale)")

  • "multinom": This multinomial outcome is complex, with one line per covariate per outcome (less the reference group)

  • "gam": Uses the internal tidier tidy_gam() to print both parametric and smooth terms.

  • "lmerMod", "glmerMod", "glmmTMB", "glmmadmb", "stanreg", "brmsfit": These mixed effects models use broom.mixed::tidy(x, effects = "fixed"). Specify tidy_fun = broom.mixed::tidy to print the random components.


The N reported in the output is the number of observations in the data frame model.frame(x). Depending on the model input, this N may represent different quantities. In most cases, it is the number of people or units in your model. Here are some common exceptions.

  1. Survival regression models including time dependent covariates.

  2. Random- or mixed-effects regression models with clustered data.

  3. GEE regression models with clustered data.

This list is not exhaustive, and care should be taken for each number reported.
