Table 1.
Comparison of ruptured group and unruptured group by cyst diameter, cyst area, and thickness of wall
| Unruptured | Ruptured | Total | Significance (p-value) | |
|---|---|---|---|---|
| Cyst diameter (mm) | 5.84±3.24 | 4.64±3.14 | 5.50±3.25 | 0.002 |
| Cyst area (mm2) | 42.70±48.79 | 29.42±38.96 | 38.89±46.52* | 0.014 |
| Thickness of wall (μm) | 71.21±64.17 | 137.23±104.72 | 90.15±83.38† | 0.000 |
*
The mean cyst area was 38.89 mm2 and the mean cyst area of the unruptured group was wider than it of the ruptured group (P<0.05);
†
The mean wall thickness was 0.09mm and the mean wall thickness of ruptured group was thicker than it of the unruptured group(P<0.05).
