MAL2 and neoplasm: Further univariable analysis showed that pathologic M stage (M0 vs. M1), pathologic stage (stage II vs. stage IV), histological type (epithelioid cell vs. spindle cell), tumor shape (diffuse vs. dome, diffuse vs. mushroom), MAL2 level (low vs. high), and MALL level (low vs. high) were prognostic factors predicting OS in UM patients (Supplementary Table S1).
