Kaplan–Meier analysis of survival rates in patients with high- or low-level NQO1 expression and with early- or late-stage cervical SCC. Disease-free survival (A) and overall survival rates (B) were assessed in patients with early-stage cervical SCC concomitant with either high- (solid, n = 44) or low-level (dashed, n = 57) NQO1 expression. Disease-free survival (C) and overall (D) survival rates were also assessed in patients with late-stage cervical SCC concomitant with high- (solid, n = 53) or low-level (dashed, n = 23) NQO1 expression.
