Replication Data for: Evolution in peak oxygen uptake and its impact on physical activities of daily living in chronic kidney disease and transplantation

The purpose of this dataset was to assess changes in cardiorespiratory fitness, specifically peak oxygen uptake (V̇O2peak) and percent-predicted V̇O2peak, across the different stages of chronic kidney disease (CKD), with the glomerular filtration rate (GFR) as a key estimate of the patients' kidney function. The data, identified through the PubMed database, was retrospectively analyzed from 192 cohorts, encompassing a total of 5757 CKD patients. The analysis aimed to investigate the decline in V̇O2peak across the spectrum of CKD, from early- to end-stage kidney failure, as well as the evolution of cardiorespiratory fitness following kidney transplantation.
