The outcome was defined as more than a 30% decrease in eGFR from baseline, CKD-related hospitalization or death, or the presence of end-stage renal disease. Quartiles of sitting time: 1st quartile ≤17.4 h/week, 2nd quartile=17.5–27.9 h/week, 3rd quartile=28.0–36.9 h/week, 4th quartile ≥37 h/week. Model 1: Crude HR. Model 2: Adjusted for age, sex, current smoking, and current drinking. Model 3: Adjusted for covariates in Model 2 plus BMI, hypertension, diabetes, dyslipidaemia and MVPA. HR – hazard ratio; CI – confidence interval.
