very nice two-punch set of papers led by @mjsaunder.bsky.social and @cfmcquaid.bsky.social. First fix the many issues with recent reviews of BMI and TB, and then follow it through on the consequences for the key PAF metrics. Undernutrition was, is and remains a key driver of global TB burden.
“Wow, I saw in the last GTB report undernutrition is much less important for TB than we previously thought” I hear you say…
Well, no. We think this is an underestimate, & as much as 28% of TB could be attributable to undernutrition – see our latest comment here: www.thelancet.com/journals/lan...
