Fig. 2 Metastasis rate of each mediastinal lymph node station (station 2, upper paratracheal; station 3, pre-vascular and retrotracheal; station 4, lower paratracheal; station 5, sub-aortic; station 6, para-aortic; station 7, sub-carinal; station 8, paraesophageal; and station 9, pulmonary ligament). A chi-square test was used to compare the metastasis rate of station 9 with other mediastinal stations. *p < 0.05; ***p < 0.001.
