For binary outcomes (Disease/No Disease; Death/Alive), the PDF must explain:
After working through the PDF, you should be able to produce: Statistical Analysis of Medical Data Using SAS.pdf
The irony is that the document you are searching for—"Statistical Analysis of Medical Data Using SAS.pdf" —is often the final deliverable of the process. In a pharmaceutical setting, after running the SAS code, the statistician must generate a report. SAS code blocks
Using ODS (Output Delivery System), SAS can create a PDF directly: publicly available NHANES
ods pdf file="C:\Clinical_Report\Statistical_Analysis_Medical_Data.pdf";
ods noproctitle;
title "Table 1: Baseline Demographics";
proc freq data=adsl; ... run;
proc ttest data=adsl; ... run;
ods pdf close;
The guide would emphasize best practices: landscape orientation for wide tables, using ODS TEXT to insert interpretation notes, and using ODS RTF as an intermediary for MS Word editing.
| Step | Action | Time Estimate | |------|--------|----------------| | 1 | Skim PDF: read all headings, SAS code blocks, and interpretation sections. | 1 hour | | 2 | Recreate 3 key examples using your own SAS environment. Start with descriptive stats and t-test. | 2 hours | | 3 | Apply to a real medical dataset (e.g., publicly available NHANES, MIMIC, or SEER data). | 3+ hours | | 4 | Write a 1-page medical summary: “SAS Analysis of [Outcome] in [Population]”. | 2 hours |
| Pitfall | How to Use the PDF |
|--------|----------------------|
| Misinterpreting p-values in medical context | Find section on clinical vs. statistical significance. |
| Ignoring missing data patterns | Review how to use PROC MI or PROC FREQ with missing flags. |
| Violating model assumptions | Check diagnostic sections (residual plots for PROC REG, proportional hazards test for PROC PHREG). |
| Overlooking multiple comparisons | Locate adjustment methods (Bonferroni, false discovery rate) using PROC MULTTEST. |
