↵5-150 Derived from univariate Cox's proportional hazards model.
↵5-151 Derived from a multivariate Cox's proportional hazards model.
↵5-152 p values for the factors are the Wald statistics for the estimates in the model, conditional on the other factors being present.
↵5-154 p values for the factors are the Wald statistics for the estimates in the model, conditional on the other factors being present.
↵5-160 Includes cases with a recorded histological type known not to be small cell lung cancer (SCLC).
↵5-164 Includes cases with type not known or not recorded and those with no microscopic verification.
↵5-161 Neither the potentially curative treatment nor surgical resection factors were offered to the multivariate Cox model.
