  1. The Wald statistics test the unique contribution of each variable; the higher the Wald statistics, the higher the association/contribution in the model
  2. *Only variables that were significant in the univariable models (log rank test) were included in the multivariable analysis (Cox regression model), with the final model containing only significant covariates in the multivariable analyses (forward stepwise selection model). For some values, the 95% CI could not be computed (−)
