	Leisure-time physical activity duration
	0 min/d	0–30 min/d	30–60 min/d	$>$60 min/d
Participants, N	2181	387	306	445
Model 3	1.00 (Reference)	0.55 (0.39–0.78)	0.27 (0.17–0.42)	0.20 (0.11–0.36)
Model 4	1.00 (Reference)	0.44 (0.19–1.01)	0.23 (0.09–0.58)	0.23 (0.08–0.63)

Model 3: unadjusted model; Model 4: adjusted for sex, blood urea nitrogen, serum potassium, heart failure, hypertension, anemia, and estimated glomerular filtration rate (according to a change in effect estimate of more than 10%).
