(A) Overall survival stratified by the type of operation in the unmatched overall cohort. (B) Overall survival in the propensity score–matched cohort. Note that the observed difference in survival (p < 0.001) in the matched cohort is mainly realized in the first year after the operation, after which the rate of decay becomes negligible (conditional p = at 18 months). (C) Overall survival in the propensity score matched cohort stratified by carcinoid vs non-small cell lung cancer (NSCLC) histology.

Risk-adjusted perioperative outcomes stratified by hospital sleeve-to-pneumonectomy (S:P) ratio quintile. Note that the outcomes are equivalent across quintiles of S:P ratios. Univariate comparisons are made between the highest and lowest quintiles.
