Fig. 5From: Distinct impacts of radiological appearance on lymph node metastasis and prognosis based on solid size in clinical T1 non-small cell lung cancerPrognostic comparison of patients with PSN and SN for cT1a (a), cT1b (b), and cT1c (c) NSCLC. For cT1a NSCLC, no significant DFS difference existed between patients with SN and PSN (P = 0.840). For cT1b and cT1c NSCLC, patients with SN had inferior prognosis than those with PSNBack to article page
