Diagnosing and Accommodating Pandemic Effects on Ongoing Research

This talk considers approaches to analysis of data from longitudinal research projects where pandemic onset occurred mid study. Once data are collected, the goals are to diagnose whether pandemic onset impacted study results and, if so, which types of effect estimates are affected. Given the diagnostic information, investigators can choose which effect estimates to report, i.e., pooled-data, pre-pandemic, and/or pandemic-era estimates. This is an expansion and improvement of a similar talk I gave as part of a CAPS Roundtable in November 2020 and includes some revised recommendations.
