3.5. Effect of probiotics on intestinal flora
To evaluate the effect of probiotics in intestinal flora, we analyzed the fatty acids and organic anions, which were metabolites of intestinal bacteria. Short-chain fatty acids and organic anions in stools relative to baseline are shown in Table Short-chain fatty acid and organic anions in stool (relative to baseline).95% CI indicated difference of fatty acids and organic anions concentration between placebo and probiotics groups (Probiotics—Placebo). To confirm the increase of Occupation ratio (relative to baseline) of microbacteria in stool.95% CI indicated difference of occupation ratio of microbacteria between placebo and probiotics groups (Probiotics—Placebo).
