Multivariate model 1: adjusted for age, sex, body mass index and the estimated glomerular filtration rate.
Multivariate model 2: adjusted for the factors of model 1, systolic blood pressure and levels of haemoglobin, albumin, uric acid, triglyceride and fasting glucose.
Multivariate model 3: adjusted for the factors of model 2 and the presence of diabetes or hypertension at baseline.
