The incidence rate and number of events (N) for the primary outcomes and for each cause of death is given in 1000 person-years. The incidence rate for cardiovascular disease included stroke, cardiac disease, and vascular disease. Uremia is defined as: main cause of death is end-stage renal disease withholding renal replacement therapy. The incidence rate and number of events (N) according to BMI group is also presented. Abbreviations: ICD-10 the 10th revision of the International Classification of Diseases, 95% CI 95% confidence interval, BMI body mass index
