ANXA1 and bladder transitional cell carcinoma: ROC curves were constructed to evaluate the prognostic prediction value of ANXA1. The results showed that ANXA1 might have a certain ability in outcome prediction of BLCA patients but low accuracy (AUC of OS: 0.626, 1-year survival: 0.665, 2-year survival: 0.658, 5-year survival: 0.640) (Additional file 1: Fig. S1A, B).
