结局指标
主要结局
Constipation symptom improvement
时间窗: 3 weeks
The Bristol Stool Form Scale (BSFS) will be used to assess improvements in constipation. The BSFS is a 9-point scale ranging from 1 to 7, where higher scores indicate softer stool consistency, approaching a liquid state. The specific scoring is as follows: 1. Separate hard lumps, like nuts (difficult to pass) 2. Sausage-shaped but lumpy 3. Like a sausage but with cracks on the surface 4. Like a sausage or snake, smooth and soft 5. Soft blobs with clear-cut edges (passed easily) 6. Fluffy pieces with ragged edges, a mushy stool 7. Watery, no solid pieces, entirely liquid Scores of 4, 5, and 6 are generally considered ideal, indicating smooth bowel movements without constipation. Therefore, higher scores (closer to 4-6) represent improved constipation symptoms, while lower scores (1-3) indicate more severe constipation.
