CharacteristicValue
a Data are expressed as mean± SD or as median (interquartile range), as appropriate. Kt/V denotes fractional urea clearance, which was calculated according to the method of Sargent and Gotch 25 for patients undergoing hemodialysis and by a standard formula 26 for patients undergoing chronic ambulatory peritoneal dialysis. BMI, body mass index; PTH, parathyroid hormone; LVM, left ventricular mass.
