1Adjusted for baseline outcome and height.
2Adjusted for baseline outcome, height, sex, age, smoking status, alcohol consumption, physical activity, education and menopausal status for women. Analysis with change in waist circumference adjusted for concurrent weight change.
3Estimates were calculated in MONICA, DCH and INTER99 using linear regression and meta-analysed using a fixed effect meta-analysis approach. Individual cohorts were weighted based on the inverses of their variances (% weight).
