Comparison of the discrimination of prediction for the progression of CKD between targeted BP, PP, and the combination of PP and targeted BP.

	Harrel’s C-index	Difference from model 1	p-value
Model 1	0.7327 (0.6986–0.7668)	–	–
Model 2	0.7356 (0.7010–0.7702)	0.0029 (− 0.0076–0.0135)	0.588
Model 3	0.7330 (0.6988–0.7672)	0.0003 (− 0.0043–0.0049)	0.854

Model 1: conventional targeted BP (< 130/80 mmHg for those with diabetes or proteinuria and < 140/90 mmHg); model 2: PP ≥ 66 mmHg; model 3: combination of PP (< 66 or ≥ 66) and/or targeted BP.

Other variables for adjustment were age, sex, BP-lowering medication, diabetes, dyslipidemia, hyperuricemia, obesity, smoking, drinking, and baseline eGFR and proteinuria.
