| Table 2. Hysteroscopic findings | ||||
| All (n=1141) |
TVS positive (n=180) |
TVS negative (n=961) |
p-value | |
| Any alteration | 351 (30.7%) | 86 (47.8%) | 265 (27.6%) | 0.000 |
| Endometrial Polyp | 170 (17.9%) | 44 (24.4%) | 126 (13.1%) | 0.000 |
| Submucous Leiomyoma | 44 (3.9%) | 20 (11.1%) | 24 (2.5%) | 0.000 |
| Uterine Synechiae | 39 (3.4%) | 9 (5.0%) | 30 (3.1%) | 0.260 |
| Uterine Malformation | 53 (4.6%) | 16 (8.9%) | 37 (3.9%) | 0.006 |
| Suspected Endometritis | 42 (3.7%) | 1 (0.6%) | 41 (4.3%) | 0.009 |
| Endometrial "thickening" | 42 (3.7%) | 9 (5.0%) | 33 (3.4%) | 0.285 |
| Other | 15 (1.3%) | 1 (0.6%) | 14 (1.4%) | 0.490 |
| The sum of all alterations is higher than the number of hysteroscopies with “any alteration” because some patients had more than one type of lesion. p-values refer to the comparison between TVS positive and TVS negative groups (Chi-square or Fisher’s exact test, as appropriate). |
