Comparison of torsion masses with non-torsion masses presenting with abdominal pain
| Variables | Torsion masses (n=14) | Non-torsion masses (n=16) | P value |
| Age (years) | 9.7 | 12.1 | 0.377 |
| WBC (x 109/L) | 10.36 | 6.5 | 0.0257 |
| CRP (mg/dL) | 0.16 | 0.05 | 0.162 |
| Mass size (cm) | 8 | 8.5 | 0.677 |
| Abdominal pain lasting (hours) | 39 | 207 | 0.261 |
Abdominal pain lasting (hours): the duration of abdominal pain (from onset to surgery).
CRP, C-reactive protein; WBC, white blood cell.
