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

Table 3

Cox regression analysis for CHF with categorized serum MMP7.

Serum MMP7 (ng/ml)	Unadjusted		Adjusted^a
	HR (95% CI)		HR (95% CI)
≤4.80	1 (refer)	—	1 (refer)	—
>4.80	1.577 (1.067-2.331)	0.02	1.595 (1.023-2.488)	0.04

Baseline serum MMP7 was categorized into two groups. BMI and KT/V were calculated by the formulas mentioned before. CHF: congestive heart failure; MMP7: matrix metalloproteinase-7; HR: hazard ratio; CI: confidence interval; BMI: body mass index; LVEF: left ventricular ejection fraction; UF: ultrafiltration; ALB: albumin. ^aAdjusted with age, sex, BMI, baseline LVEF, baseline UF, baseline total KT/V, loss of residual renal function, mean dialysate glucose concentration, and serum ALB of the first 12 months after dialysis.
