Univariate and multivariate logistic analyses showed that station 10 LNM, tumor location, and the number of resected lymph nodes were independent risk factors associated with station 3A LNM. Before PSM, patients with station 3A LND had worse 5\u2010year OS (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.002) and DFS (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.011), and more drainage on postoperative day 1 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.041) than those without.
