Survival was analyzed from the time of transplantation to a maximum of 7 years, with kidney-graft reduction as the event of interest. Data on graft survival were censored at the time of death. Cox proportional-hazards versions were utilized to quantify hazard ratios and 95 percent self-confidence intervals for kidney-graft reduction. The association of clinical, histologic, functional, and immunologic factors with graft loss was assessed in distinct univariate and multivariate Cox regression analyses. The factors determined in these analyses were contained in your final multivariable model with stepwise backward elimination thereafter.
