Table 5. Validity indicators for CA-125 and RMI at different cut-offs for all patients with malignant ovarian tumors (n= 61).

Test	Cut-off	Sensitivity (%)	Specificity (%)	NPV	PPV	Efficiency
CA-125 U/ml	35	69	68	92	31	69
	50	61	75	90	33	68
	70	54	82	90	38	68
RMI	150	62	78	91	37	70
	200	57	81	90	38	69
	250	54	85	90	42	70

CA-125: cancer antigen 125; RMI: risk of malignancy index; NPV: negative predictive value; PPV: positive predictive value
