PCT = potentially curative treatment.
↵4-150 In separate logistic regression models.
↵4-151 In a multivariate logistic regression model.
↵4-152 p values for the factors are the Wald statistics for the estimates in the model.
↵4-154 p values for the factors are the Wald statistics for the estimates in the model, conditional on the other factors being present.
↵4-160 Includes cases with a recorded histological type known not to be SCLC.
↵4-164 Includes cases with type not known or not recorded and those with no microscopic verification.
