^aRegression coefficient

Model 1: Adjusted for age and sex.

Model 2: Adjusted for Model 1 plus dialysis vintage, diabetes, haemoglobin, albumin, CCI, total KT/Vurea per week, renal CrCl, nPNA, 24-h urine volume and the baseline OH value.

Model 3: Adjusted for Model 2 plus baseline scores of PCS, MCS, and KDCS, respectively.
