Kaplan-Meier survival curves and comparisons of survival rates by log-rank test.

<p>(A) Mortality rates gradually increased with the increment of age categories (<i>P = </i>0.0000). (B) Females showed better survival rate compared to males (<i>P = </i>0.0004). (C) Survival rate was better for patients without diabetes than that with diabetics (<i>P = </i>0.0000). (D) Patients covered by National Health Insurance experienced higher better survival rate compared to Medical Aid beneficiaries (<i>P = </i>0.0000). (E) Patients on hemodialysis experienced significant survival benefit over patients on peritoneal dialysis in the intention-to-treat analysis (<i>P = </i>0.0000). (F) As the modified Charlson comorbidity index for end-stage renal disease patients increased, survival rates significantly decreased (<i>P = </i>0.0000).
