A SAS programmer needs to perform a one-way ANOVA to compare mean blood pressure levels across three different treatment groups. The dataset 'clinic_bp' contains variables 'treatment' (categorical variable for treatment groups) and 'bp' (continuous variable for blood pressure measurements). Which SAS procedure should the programmer use to produce the appropriate analysis?

When using PROC REPORT to summarize clinical trials data, you want to add a summary row at the end of each BY group as well as a grand total at the end of the report. Which combination of BREAK and RBREAK statements would correctly achieve this?

You have been given a raw dataset that contains date variables in various formats. During validation, you want to ensure that all date variables are uniformly formatted as per the study requirements before they are used for generating reports. Which of the following SAS procedures would allow you to examine all date values across the dataset to confirm they adhere to the specific date format "MMDDYY10.?"

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?

You are tasked with producing a series of Forest plots to graphically display the results of a subgroup analysis in a clinical study using PROC SGPLOT.
