According to the protocol of at least three groups of mediastinal lymph nodes dissection recommended by National Comprehensive Cancer Network guidelines, a total of 485 patients were selected for statistical analysis.

^a: Right upper lobe+Right middle lobe vs Right lower lobe between the same sites; ^b: Left upper lobe vs Left lower lobe between the same sites.
