You have two SAS datasets, 'baseline' and 'followup', that are supposed to have the same structure and variable attributes. However, discrepancies are suspected. You need to compare the datasets to see if there are any differences in the attributes of the variables. Which PROC COMPARE option would you use to display only those variables that differ, without listing those that match?

A clinical trial analyst needs to create a Kaplan-Meier survival plot to visualize the time-to-event data for different treatment groups. Which PROC step should the analyst use, and what is the key statement to differentiate the treatment groups in the graph?

A clinical trial dataset contains the variable 'BloodPressure' measured at multiple time points for patients. You are interested in analyzing the distribution and central tendency of baseline blood pressure levels across all patients. Which SAS procedure would you use to generate descriptive statistics including the mean, median, standard deviation, and quartiles for the baseline 'BloodPressure' measurements?

In a clinical trial, the variable 'TreatmentGroup' indicates whether a patient received the experimental drug (coded as 'Drug') or the placebo (coded as 'Placebo'). You have been tasked with reporting the frequency and percentage of patients in each treatment group. Which SAS procedure would allow you to obtain these specific statistics for categorical data?

Suppose you are working on a project that requires creating a customized table that is not readily available from any SAS procedures, but you can generate the needed statistics. You need to capture these statistics in a dataset for further manipulation. Which ODS OUTPUT destination would you use to redirect the output of PROC MEANS to capture the necessary summary statistics in a SAS dataset?
