|---|---|---|---|
| Endometrial thickness (ET) | 18.9 ± 8.3 | 15.3 ± 10.8 | 0.028* |
| ET <5mm | 0 (0) | 5 (2.6) | 0.587† |
| 5 ≤ET <10mm | 7 (13.7) | 57 (29.5) | 0.022ǂ |
| 10mm ≤ET <20mm | 22 (43.1) | 78 (40.4) | 0.725ǂ |
| 20mm ≤ET <30mm | 18 (35.3) | 40 (20.7) | 0.030ǂ |
| ET ≥30mm | 4 (7.8) | 14 (7.3) | 1.000† |
| Polypoid mass like lesion | 5 (9.8) | 96 (49.7) | 0.000* |

Group A included patients with endometrial cancer; group B included patients with non-malignant lesions; values are presented as mean ± standard deviation or number (%); *p-value obtained by student t-test; †p-value obtained by Fisher's exact test; ǂp-value obtained by Chi-square test; p-value of less than 0.05 was considered to be significant
