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

Figure 7

Kaplan-Meier curves for PD withdrawal and combined endpoint. Participants were categorized into two groups according to baseline serum MMP7 levels (,  ng/ml; ,  ng/ml). The Kaplan-Meier survival function curves showed a higher cumulative incidence of PD withdrawal () and combined endpoint () in participants with increasing levels of baseline serum MMP7. PD withdrawal was defined as death, transfer to hemodialysis, or renal transplantation. Combined endpoint was defined as death, CHF, cardiovascular diseases, or stroke. MMP7: matrix metalloproteinase-7; PD: peritoneal dialysis; HR: hazard ratio; CI: confidence interval; CHF: congestive heart failure.
