- Results for the multivariate Cox model, stratified for year of birth (saturated model with 23 variables which were significant at p > 0.25 in univariate analysis. The most parsimonious model was selected manually using log-likelyhood ratio test). Automated forward and backward stepwise elimination were consistent with the manual procedure above. Analysis time: 563.68 person-years. Proportional hazards assumption was checked (Schoenfeld: p = 0.862)
