BMI: Body mass index; ABSI: A body shape index; Ref: Reference; CI: Confidence interval
Model 1: Unadjusted model
Model 2: Adjusted for baseline age, smoking, education, and physical activity status
Time variable means follow-up visits
^aThe results of ABSI are presented by z-scores
^bSignificant p-values (p < 0.05) are bolded
