Table 4 Results of multivariate regression analyses of predictors for UTI.

From: Stented ureterovesical anastomosis in renal transplantation: does it influence the rate of urinary tract infections?

Variable Coefficient in Initial regression model P value Coefficient in final regression model (with 95%-CI) P value
Age (per year increase) 0.998 0.93 -  
Gender (male vs. female) 0.395 0.002 0.40 (0.23 to 0.70) 0.001
BMI (per kg/m 2 ) 1.005 0.88 -  
Diabetes 1.0 1.0 -  
"Extra risk" recipients 1.625 0.33 1.68 (0.95 to 2.97) 0.077
Duration of pretrans-plant dialysis (per month increase) 0.998 0.59 -  
Duration of surgery (per minute increase) 1.001 0.75 -  
Urinary stenting 1.169 0.62 -  
Tacrolimus 0.986 0.964 -  
Cold ischemia time (per minute increase) 0.980 0.307 -  
  1. Explanatory power of the final model was limited, as Nagelkerke's R2 was 0.08.
