Question 2
-
During a clinical trial, data were collected on a nominal categorical variable indicating patients' blood type (Type A, Type B, Type AB, Type O). The goal is to analyze the distribution of blood types among patients who experienced an adverse event versus those who did not. Which of the following statistical methods BEST suits the objective of comparing the distribution of a nominal categorical variable across two independent groups?

Question 5
-
A clinical trials programmer is tasked with creating a Kaplan-Meier survival plot with a log-rank test for comparing survival curves between two treatment groups. The dataset includes patient ID, treatment group, time to event or censor, and the event indicator. Which PROC step will they likely use to produce the required output?
