This conclusion is based on data from over 800,000 people tracked for up to 26 years, with researchers adjusting for many other health factors, making the results very reliable.
Scientific Claim
The pooled hazard ratios for mortality outcomes are based on multivariable-adjusted models from 16 prospective cohort studies with long follow-up periods (4.6–26 years) and large sample sizes (n=833,234), enhancing the reliability of the observed associations.
