Wondering how patient survival data is analyzed in clinical research?

Have you always wondered how survival estimates are calculated?

In this course, Statistician Robin Ruthazer, MPH, will present a behind-the-scenes look at survival analysis. Learn how time-to-event data requires special techniques like Kaplan-Meier curves and Cox regression, and how their output is interpreted.
