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

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?

enter image description here

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

Solution

  • 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

    table with dash for confidence interval instead of comma
