: Subtype clinical and morphological characteristics.

Patient characteristics are summarized over all cohorts. The number of patients having a characteristic (n) varies because all cohorts do not include all characteristics. The percent statistics indicate the percent of tumors in a subtype having a given characteristic, e.g. 75% of the tumors in the Bronchioid subtype are stage I. The percentage characteristics refer to percentage values given to individual tumors, and subtype median values are presented, e.g., the median papillary percentage of tumors in the Bronchioid subtype is 51. Categorical and continuous variables were compared by Fisher's exact tests and Kruskal-Wallis tests, respectively (*: two-sided PP
