Prediction of Factors Associated with Abnormal Uterine Bleeding by Transvaginal Ultrasound Combined with Bleeding Pattern

Figure 6

Prediction efficiency of endometrial hyperplasia and canceration. A3: prediction of individual bleeding patterns: irregular bleeding. B3: vaginal ultrasound alone predicted: endometrial  mm, increased uterine echo, and no three-line sign. C3: prediction of irregular bleeding pattern combined with vaginal ultrasound.
