Matrix Metalloproteinase-7 Associated with Congestive Heart Failure in Peritoneal Dialysis Patients: A Prospective Cohort Study

Table 4

Cox regression analysis for PD withdrawal and combined endpoint.

Variables	PD withdrawal		Combined endpoint
	HR (95% CI)	^a	HR (95% CI)	^b
Serum MMP7, ng/ml	1.090 (1.028-1.550)	0.004	1.083 (1.011-1.580)	0.02
Ln dialysate MMP7, pg/ml	1.468 (1.152-1.870)	0.002	1.532 (1.131-2.076)	0.006

KT/V was calculated by the formulas mentioned before. PD: peritoneal dialysis; MMP7: matrix metalloproteinase-7; HR: hazard ratio; CI: confidence interval; DKD: diabetic kidney disease; ESRD: end-stage renal disease. ^aAdjusted with demographics (age and sex), the mean values of dialysate glucose concentration, urine volume, serum creatinine, serum phosphate, hemoglobin, and KT/V during the first 12 months after dialysis. ^bAdjusted with demographics (age and sex), DKD to ESRD, the mean values of dialysate glucose concentration, urine volume, serum albumin, serum phosphate, hemoglobin, and KT/V during the first 12 months after dialysis.
