  1. Endometrial thickness: Group 1: ≤7 mm; Group 2: >7 mm to ≤14 mm; Group 3: >14 mm.
  2. Pattern A was defined as a triple-line pattern consisting of a central hyperechoic line surrounded by two hypoechoic layers. Pattern B was defined as an intermediate isoechogenic pattern with the same reflectivity as the surrounding myometrium and a poorly defined central echogenic line. Pattern C was defined as homogenous, hyperechogenic endometrium.
  3. NS: not significant
