Table 2 A multivariate Cox proportional-hazards regression model for predictive of time to CRBSI onset in the crude population.

From: Effect of sutureless securement on hemodialysis catheter-related bloodstream infection

Explanatory variables

Hazard ratio [95% confidence interval]

P value

Catheter securement method (Suture: 0, GRIP-LOK: 1)

0.20 [0.04–0.95]*

0.043

Propensity scores

1.28 [0.08–19.7]

0.858

  1. Propensity scores was calculated from age, sex, dialysis history, AKI, diabetes, immunosuppressive drugs, catheterization site, MRSA carriage, bacteremic event within 3 months before catheterization, and aspirin.
  2. CRBSI catheter-related bloodstream infection.
  3. *Propensity scores—adjusted Hazard ratio.
