- Endometrial thickness: Group 1: ≤ 7 mm; Group 2: >7 to 14 mm; Group 3: >14 mm
- Pattern A = triple-line pattern, hypoechoic endometrium with well-defined hyperechoic outer walls and central echogenic line
- Pattern B = no-triple line pattern, isoechogenic or homogeneous hyperechoic endometrium with a poorly defined or absent central echogenic line
- CPR = clinical pregnancy rate
- aPregnant cycles/total cycles and percentage of clinical pregnancies
- bP-values by chi-square text
- NS = not significant
