In gtsummary: Presentation-Ready Data Summary and Analytic Result Tables

Add event N

Description

Add event N

Usage

add_nevent(x, ...)

## S3 method for class 'tbl_regression'
add_nevent(x, location = "label", ...)

## S3 method for class 'tbl_uvregression'
add_nevent(x, location = "label", ...)

Arguments

x	(tbl_regression, tbl_uvregression) a tbl_regression or tbl_uvregression table
...	These dots are for future extensions and must be empty.
location	(character) location to place Ns. Select one or more of c('label', 'level'). Default is 'label'. When "label" total Ns are placed on each variable's label row. When "level" level counts are placed on the variable level for categorical variables, and total N on the variable's label row for continuous.

Examples

# Example 1 ----------------------------------
trial |>
  select(response, trt, grade) |>
  tbl_uvregression(
    y = response,
    exponentiate = TRUE,
    method = glm,
    method.args = list(family = binomial),
  ) |>
  add_nevent()

# Example 2 ----------------------------------
glm(response ~ age + grade, trial, family = binomial) |>
  tbl_regression(exponentiate = TRUE) |>
  add_nevent(location = "level")
