Fig. 2From: Evaluation of log odds of positive lymph nodes in predicting the survival of patients with non-small cell lung cancer treated with neoadjuvant therapy and surgery: a SEER cohort-based studyKaplan–Meier estimates of OS of patients with NSCLC who received neoadjuvant therapy stratified by N classification (A) and LODDS (B) before IPTW. OS, overall survival; NSCLC, non-small cell lung cancer; LODDS, log odds of positive lymph node; IPTW, inverse probability of treatment weightingBack to article page
