SP controlled duration, months	0.971 (0.959–0.984)	<0.001	0.968 (0.956–0.981)	<0.001
SP controlled duration, years	0.640 (0.533–0.770)	<0.001	0.619 (0.512–0.748)	<0.001
Age, years	1.033 (1.018–1.049)	<0.001	1.017 (1.000–1.035)	0.055
Male	1.338 (0.852–2.101)	0.207	1.409 (0.821–2.420)	0.214
DKD to ESRD	2.286 (1.404–3.730)	0.001	2.166 (1.241–3.780)	0.007
Mean MAP, mmHg	0.963 (0.943–0.984)	0.001	0.963 (0.942–0.986)	0.001
Mean dialysate GLUC, %	4.702 (1.702–9.747)	0.002	1.632 (0.577–4.617)	0.356
Mean urine volume, L	0.495 (0.280–0.874)	0.015	0.712 (0.345–1.468)	0.357
Mean serum ALB, g/L	0.905 (0.874–0.936)	<0.001	0.906 (0.869–0.945)	<0.001
Mean HGB, g/L	0.986 (0.973–0.999)	0.033	0.996 (0.984–1.008)	0.520
Mean KT/V	0.483 (0.299–0.781)	0.003	0.983 (0.622–1.555)	0.943

MAP and KT/V were calculated by formulas mentioned before. Mean MAP, dialysate GLUC, urine volume, serum ALB, HGB, and KT/V were the average values during the first 12 months after dialysis. HR, hazard ratio; CI, confidence interval; SP, serum phosphorus; DKD, diabetic kidney disease; ALB, albumin; HGB, hemoglobin; MAP, mean arterial pressure.

^aAdjusted for demographics (age and sex), DKD to ESRD, and the mean values of MAP, dialysate GLUC, urine volume, serum ALB, HGB, and KT/V during the first 12 months after dialysis.
