Dear researchers,
It is my first post.
I used stata code to calculate 95%CI for proportion to calculate the proportion of the annual total number of death/ total number of patients diagnosed with stroke in the study year.
Code: ci proportions
In this code, what kind of assumption (distribution) does STATA use to calculate CI?
I have been searching for it, but I could not find the answer.
Sorry for such a basic question, but I appreciate your help.

Kind regards,
Yumi TOMARI
