a
Multivariable Cox regression model of OS adjusted for age, smoking history, differentiation degree, high-risk subtype, and GGO component. Multivariable Cox regression model of DFS adjusted for age, tumor size, differentiation degree, number of N1 station examined, high-risk subtype, and GGO component.
