Data are presented as n (%) or mean ± SD.
a Weight loss subgroup defined as >3% of body weight lost.
b Weight stable subgroup defined as within ±3% body weight change (gain or loss).
c Weight gain subgroup defined as >3% of body weight gained.
d The 10-yr risk of a first CVD event among ≥30 yr olds estimated from risk functions published in 2008 using data from the Framingham Heart Study and the Framingham Offspring Study.
