[Correspondence] Body-mass index and all-cause mortality

In The Lancet (Aug 20, p 776),1 the Global BMI Mortality Collaboration reported a meta-analysis of mortality outcomes across different body-mass index (BMI) categories for more than 10 million participants from 239 prospective studies. In their primary analysis, the authors aimed to reduce both confounding and reverse causality by including only those people who were never smokers, who did not have chronic disease, and who had at least 5 years of follow-up data (3·95 million people [37%] were recruited of the 10·6 million total participants).
