Fig 1: (a) Kaplan–Meier curves for progression-free survival (PFS) of EOC patients. There was a trend towards shorter PFS in patients in the high RECQL1 expression group compared with that in patients in the low RECQL1 expression group, but the difference was not statistically significant (P = 0.074). (b) Kaplan–Meier curves for overall survival (OS) of EOC patients. Patients in the high RECQL1 expression group showed significantly shorter OS compared with those in the low RECQL1 expression group (P = 0.027). EOC epithelial ovarian cancer, MST median survival time, NR not reached.
