Comparing Average Values of Colon Transit Time Test and Barium Enema
| Total (N = 70) | < 4 yr (n = 16) | ≥ 4 yr (n = 54) | P-value | |
|---|---|---|---|---|
| Colon length (cm) | 59.00 (53.75–64.00) | 54.00 (51.00–59.00) | 61.00 (55.00–66.00) | 0.002 |
| CTT (hr) | 36.00 (22.50–54.30) | 29.40 (24.30–46.80) | 37.80 (21.30–57.90) | 0.429 |
| CTT velocity (cm/hr) | 1.57 (1.07–2.89) | 1.74 (1.08–2.31) | 1.48 (1.03–2.93) | 0.922 |
| BE velocity (cm/hr) | 1.58 (0.94–2.07) | 1.76 (0.39–2.02) | 1.55 (0.94–2.11) | 0.817 |
CTT, colon transit time; BE, barium enema.
Values are expressed as median value (interquartile range).
