Model 1: Outcome—surgery within 1 month before and 6 months after diagnosis adjusted for covariates.

Model 2: Outcome—mortality within 1 year after diagnosis adjusted for covariates.

Model 3: Model 2, adjusted for surgery (patient level).

Model 4: Model 2, adjusted for spending on lung cancer (PCT level) per 1000 patients.
