Tuberculosis case-finding and diagnostics

Published on this site

2026-09-26

While focusing primarily on tuberculosis-related trials in the Division of Tuberculosis Elimination, I started to branch out into TB-related laboratory methods and case-finding. When Kevin Cain asked whether recursive partitioning could improve evidence for how to find persons with HIV at particular risk of developing TB, I was hooked. I invented a brute-force method to evaluate millions of screening rules. After our results appeared in the New England Journal of Medicine, I collaborated on a 12-study meta-analysis of case-finding that moved a 2007 World Health Organization (WHO) recommendation based on expert opinion to a 2011 WHO recommendation based on meta-analytic evidence. I turned my story about one statistician’s contributions into a testimony of exhortation to Bard College’s 2011 first-year optimists, how I carried through on my values as a scientist in contribution to evidence for finding TB to stop TB.

I also extended my thinking about diagnostics in clinical trials to diagnostics for case-finding. I perceived that laboratorians and statisticians tended to approach the same data with different orientations. A microbiologist might ask, What does the result from this specimen say about how this person should receive care? A statistician might ask, What does the result from this specimen contribute to our understanding of similar results among everyone like this person? I coined a notion of data-whispering for gentling meaning from complex laboratory data, and I invented a few novel visual representations along the way.

I developed the brute-force method for finding combinatorial, or “m-of-n”, symptom based rules for screening. I outlined the method and finding in 20110113_find-tb-stop-tb and then led a meta-analysis that incorporated this study’s findings with others’.

I love the scale of this analysis: dozens of laboratory results about each of ~32 children with HIV. We didn’t let the underdetermination stop us from figuring out what the data could and could not tell us. I used resampling methods extensively and presented the results graphically, first in 20151029_dashes-dots-small-data-graphics, then analytically in 20191024_all-your-base-r, and as antiphony between graphics and analysis in 20220419_composing-graphics-literary.
