I was wondering wether it is possible to get for all levels of Grade variable, as in this example, all regression results. Thus this would mean even including the values for level I of the Grade variable?
Example
library(nlme)
data(Orthodontic)
library(gtsummary)
glm(response ~ age + grade, trial, family = binomial(link = "logit")) %>%
tbl_regression()
In essence the question is: is it possible to add the results when Grade equal to I is not used as a referred, I mean for all the estimates computed by the model?
