In longitudinal studies, outcomes of interest are often truncated by death, meaning that they are only observed or well-defined conditional on intercurrent events such as survival.…
On the choice of using raw or demographically-corrected scores

Determining whether vaccine efficacy wanes is important for individual and public decision making. Yet, quantification of waning is a subtle task. The classical approaches cannot b…
A simple strategy for valid inference in target trial emulations
Mats Julius Stensrud
Target trial emulation has improved comparative effectiveness research by making the causal question, assumptions, and analysis plan explicit. However, target trial protocols are u…
Effects conditional on post-treatment events generated by independent mechanisms
Marco Piccininni, Mats J. Stensrud
In both observational studies and randomized trials, post-treatment events such as dropout, nonadherence, and truncation by death occur frequently. In some studies, conditioning on…
