Figure 5

Prediction efficiency of endometrial polyp. A2: prediction of bleeding pattern alone: interstitial bleeding. B2: prediction of vaginal ultrasound alone: uneven local echo in uterine cavity with three-line signs. C2: prediction of intermenstrual bleeding pattern combined with vaginal ultrasound.
