  • Adjusted for step count values from last three annual visits (t−1, t−2, t−3) and baseline covariates (age, sex, race, region, smoking status, waist circumference, systolic blood pressure, pulse pressure, chronic obstructive pulmonary disease, atrial fibrillation/flutter, low-density lipoprotein and high-density lipoprotein cholesterol, platelets, haemoglobin, log of albumin/creatinine ratio, sodium, estimated glomerular filtration rate, ECG abnormalities, congestive heart failure, cerebrovascular disease, coronary heart disease, pulmonary disease, peripheral artery disease and family history of diabetes).

  • Weight expressed per kg and step count per 2000 steps.
