结局指标

主要结局

Proportion of subjects that produce hard or lumpy stools (Bristol stool form scale (BS) score of 1 or 2) ≥ 25% of bowel movements

时间窗: During four weeks from the date of the site visit to submit a baseline stool sample.

Overall treatment effect during the intervention period will be estimated using mixed effects logistic regression (with a random intercept) which include "Groups (Yakult/non-treatment)", "Weeks (first/second two weeks of the intervention period)", "baseline (median BS score during baseline)" and "Gender (women/men)" as the independent variables. "Groups x Weeks" interaction will not be included because it was absent in the past RCT studies giving Yakult.

次要结局

  • Stool frequency with hard or lumpy one (BS score of 1 or 2)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency with ideal stool (BS score of 4)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency, as measured by a daily stool diary(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency with straining during evacuation, as measured by a daily stool diary (Yes/No)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency with sensation of remaining stool in the rectum after the evacuation, as measured by a daily stool diary (Yes/No)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency with sensation of anorectal blockage, as measured by a daily stool diary (Yes/No)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool frequency with which manual maneuvers are used, as measured by a daily stool diary (Yes/No)(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Chinese Constipation Questionnaire score(During four weeks from the date of the site visit to submit a baseline stool sample.)
  • Stool microbiota (increase in the abundance of bifidobacteria)(During four weeks from the date of the site visit to submit a baseline stool sample.)
