Clinical significance of coagulation indexes in ovarian cancer (OV) prognosis. A The flowchart of OV patient enrollment. B The Receiver operating characteristic (ROC) curves of coagulation variables including thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, international normalized ratio (INR), and the combination of fibrinogen and international normalized ratio (F-INR) for predictive recurrence-free survival (RFS, left) and overall survival (OS, right) among OV patients. C The relationship between F-INR and the International Federation of Gynecology and Obstetrics stage (FIGO stage, left, up), pathological grade (right, up), histological type (left, bottom), and tumor size (right, bottom). D The univariate (up) and multivariate (bottom) Cox Hazards Regression analysis for OS in OV patients. E. The Kaplan–Meier survival curves classified by the F-INR for RFS (left) and OS (right) among all OV patients. HR, hazard ratio; 95% CI 95% confidence interval
