statistical significant; Obesity defined as body mass index (BMI, body weight (kgs)/ height (meter)2) more than 24.9; OCP, oral contraceptive pill; RMI score (malignancy risk index) is calculated based on the serum CA 125 value, menopausal status (M), and evaluation of ultrasound (U). The formula is: RMI, U x M x CA125.
