For this meeting, we will continue our discussion on the paper about restricted mean survival time (RMST) for left truncated data, with a focus on real data analysis. The authors used the surveillance, epidemiology, and end results (SEER)-medicare data, and we will discuss the challenge of using such observational data. The reference paper is attached. If you miss the last meeting, don't worry! We will start the meeting by briefly reviewing their method.
