The RRs are based on an interquartile range change in each continuous risk factor during a 5‐year follow‐up from each examination. BMI indicates body mass index, CI, confidence interval; HDL, high‐density lipoprotein; LDL, low‐density lipoprotein, MI, myocardial infarction; RR, rate ratios; SBP, systolic blood pressure.
