Insert dash in confidence interval instead of comma in R (gtsummary)

Question

I am doing a logistic regression table with tbl_regression (gtsummary package). However, confidence intervals are displayed with a comma in between. Is there a way to put a dash instead?

So that it would be displayed 1.04 - 1.05 instead of 1.04, 1.05.

Answer 1

I would consider creating a custom theme with gtsummary. One of the theme elements is ci.sep which is the:

string indicating separator between upper and lower bounds of confidence intervals

The default is a comma, and could be set to endash or other. Other journal themes may already consider this for confidence intervals.

Here is an example using trial data from the package.

library(gtsummary)

m1 <- glm(response ~ age + stage, trial, family = binomial)

my_theme <-
  list(
    "pkgwide-str:ci.sep" = " - "
  )

set_gtsummary_theme(my_theme)

tbl_regression(m1, exponentiate = TRUE)
  

Output
