Difference in BMI (kg/m2) per 10 points of the weighted GRS, adjusted for age, genotype data source, and disease status.
Data are based on first 2 year of follow-up after the assessment of physical activity in women and men (1986-1988).
Data are based on 10 years of follow-up in women and men (1986-1996, repeated measures analysis)
Results were pooled between women and men by inverse-variance–weighted, fixed-effects meta-analyses.
