a Data are expressed as median and shown for all 235 patients and for 184 patients after those with diabetes are removed. Both groups of patients are split into early and late start groups by the median eCCr at start of dialysis. Mann Whitney U test used in all cases. Number of patients with missing variables are shown in brackets.
