Kaplan-Meier analysis of the survival rate of patients with epithelial ovarian carcinoma. The y-axis represents the percentage of patients; the x-axis, their survival in months. a Overall survival of all patients in relation to VM (log-rank = 19.072, P < 0.001); b Overall survival of all patients in relation to ALDH1 expression (log-rank = 73.845, P < 0.001); c Overall survival of all patients in relation to KiSS-1 expression (log-rank = 29.001, P < 0.001); d Overall survival of all patients in relation to MACC1 expression (log-rank = 118.775, P < 0.001). In a, b, and d analyses, the green line represents patients with positive expression of VM, or ALDH1, or MACC1 with a trend of worse survival time than the blue line representing the negative VM, or ALDH1, or MACC1 group. In d analyses, the green line represents patients with positive expression of KiSS-1 with a trend of better survival time than the blue line representing the negative KiSS-1 group. e Overall survival of all patients in relation to the combination of KiSS-1, ALDH1, VM, and MACC1 expression (log-rank = 87.116, P < 0.001). The green line represents negative expression of KiSS-1 and positive expression of ALDH1, VM, MACC1 and the blue line represents positive expression of KiSS-1 and negative expression of ALDH1, VM, MACC1. The red line represents other positive or negative expression of the proteins
