The following SAS code example, while beyond the book's introductory scope, illustrates the kind of advanced survival analysis possible with SAS. It estimates net survival for cancer patients using specialized macros, demonstrating the flexibility and power of the environment for complex survival data:

Standard regression fails when data is "censored" (e.g., a patient leaves a study before dying or the study ends before the event occurs). Statistical Analysis of Medical Data Using SAS.pdf

The descending option ensures SAS models the probability of the occurrence ( 1 ) rather than the absence ( 0 ) of a cardiac event. The output yields adjusted Odds Ratios (OR) alongside 95% confidence intervals for every risk factor included.

Originally published in 2006 and later revised in an edition titled Applied Medical Statistics Using SAS , this book is a cornerstone for anyone looking to master the application of SAS in medical research. The work is widely recognized for its practical, hands-on approach. Each chapter addresses a specific analytical method, providing a brief theoretical overview before diving deeply into its SAS implementation and, critically, how to properly interpret the output.
