Consistency of SBMs at Week 1
Tidsramme: at Week 1
|
Stool consistency was rated according to the 7-point Bristol Stool Form Scale: Type 1 = separate hard lumps, like nuts (hard to pass), Type 2 = sausage-shaped but lumpy, Type 3 = like a sausage but with cracks on the surface, Type 4 = like a sausage or snake, smooth and soft, Type 5 = soft blobs with clear-cut edges (passed easily), Type 6 = fluffy pieces with ragged edges, a mushy stool, Type 7 = watery, no solid pieces; entirely liquid.

Mean Change From Baseline in Stool Consistency at Week 1
Tidsramme: Baseline and Week 1
|
Stool consistency was rated according to the 7-point Bristol Stool Form Scale: Type 1 = separate hard lumps, like nuts (hard to pass), Type 2 = sausage-shaped but lumpy, Type 3 = like a sausage but with cracks on the surface, Type 4 = like a sausage or snake, smooth and soft, Type 5 = soft blobs with clear-cut edges (passed easily), Type 6 = fluffy pieces with ragged edges, a mushy stool, Type 7 = watery, no solid pieces; entirely liquid.
The change from baseline was calculated as post-treatment value (mean) minus the baseline value (mean).

Overall Straining at Week 1
Tidsramme: Week 1
|
Bowel straining was rated on a scale of 0 to 4 (0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe).
