HSPB2 and urinary bladder neoplasm: Moreover, ROC curve analysis confirmed the ability of HSPB2 and HSPB3 expression to discriminate bladder tumors from normal urothelium, also highlighting the superior value of HSPB2 (AUC: 0.815, 95% CI: 0.740–0.891, p < 0.001) as compared to HSPB3 gene expression levels (AUC: 0.659, 95% CI: 0.568–0.750, p = 0.003).
