  • Effects are presented as HR for chronic kidney disease with 95% CI.

  • Participants with very low-PA level comprised the reference group.

  • *The effects were estimated after adjustment for age, sex, baseline estimated glomerular filtration rate, smoking status, alcohol consumption, vegetable and fruit intake, calendar season, calendar year, body mass index, hypertension, diabetes, dyslipidaemia, self-report of a physician diagnosis of cardiovascular disease, self-report of a physician diagnosis of cancer, and urinary protein level.

  • CI, confidence interval; HR, hazard ratio; PA, physical activity.
