Data are shown mean (SD). All % predicted values control for age, gender, weight.
AT, Anaerobic threshold; CKD, chronic kidney disease; CPET, cardiopulmonary exercise testing; eGFR, estimated glomerular filtration rate; VCO2, carbon dioxide production; VE, ventilation; VO2peak, peak oxygen consumption.
