Clarke AL, et al. - This cohort study draws on data from the QCKD study (Physical activity opinions in kidney disease), a prospective observational mixed methods study to investigate connections between self-reported physical function and survival in patients with chronic kidney disease (CKD). For this investigation, 450 patients with CKD not requiring RRT, ages 17–93 years, were followed up for a median of 43 months. Findings suggested an independent association between physical function and walking behaviors with survival in CKD, and might help to identify patients at risk for adverse events.
