Journal Club: Sampling-Based Approach to Determining Outcomes of Patients Lost to Follow-Up in Antiretroviral Therapy Scale-Up Programs in Africa

This week’s paper for journal club is short and has a nice figure:

Geng et al, Sampling-Based Approach to Determining Outcomes of Patients Lost to Follow-Up in Antiretroviral Therapy Scale-Up Programs in Africa
naive_and_corrected

It looks like this corrected estimate is quite different than the uncorrected version!

I think the mathematics involved have an extended treatment in this work referenced by Geng et al: Addressing an idiosyncrasy in estimating survival curves using double-sampling in the presence of self-selected right censoring

    Two basic questions for readers: What does it mean, to be “lost to follow-up”? What is a probability weight?

    Related to answering the latter: paper and discussion of survey weights linked from an old HA blog — https://healthyalgorithms.com/2011/05/24/journal-culture/
