When data are informatively missing (or missing not at ran dom)\, however\, standard methods cannot be relied upon to guarantee valid estimation and inference. In such settings\, double-sampling facilitates the collection of additional data which\, coupled with appropriate assumpt ions\, may provide a means to perform valid causal inference. In this work we present recent methodologic developments on the use of double sampling towards estimation and inference regarding causal average treatment effec ts and weighted quantile treatment effects. The work is motivated by and i llustrated with an EHR-based study of long-term outcomes following bariatr ic surgery.\n\nSpeaker Bio\n\nDr. Haneuse is a Professor of Biostatistics and Director of Graduate Studies\, overseeing the PhD program at Harvard T .H. Chan School of Public Health. He is an AE for Biometrics\, and Statist ical Editor for JAMA Network Open.\n For more information please visit: htt ps://www.hsph.harvard.edu/profile/sebastien-haneuse/ \n\n \n DTSTART:20231108T203000Z DTEND:20231108T210000Z SUMMARY:Double sampling for informatively missing data in EHR-based compara tive effectiveness research URL:/epi-biostat-occh/channels/event/double-sampling-i nformatively-missing-data-ehr-based-comparative-effectiveness-research-352 447 END:VEVENT END:VCALENDAR
