Random forest analysis identifying factors associated with postoperative LMD. A: A random forest model using bootstrapping to predict postoperative LMD was created using a training cohort (n = 152 patients), and a separate testing cohort (n = 65 patients) was used to validate the model. AUROCs for the training and testing cohorts were 0.94 and 0.87, respectively. B: The top three factors associated with LMD occurrence were tumor location, systemic disease status, and surgically resected tumor volume.
