Association of fat mass and fat‐free mass with all‐cause and cause‐specific mortality in Asian individuals: A prospective cohort study
Authors' conclusion
The mortality risk increases in those with excessively high or low FMI and FFMI, yet the associations between FMI, FFMI, and the risk of death varied across subgroups and causes of death.
