What the trial is, and whether it could suit you
This study was conducted in two phases. In Phase I, 40 UC participants, 40 CD participants, and 40 colitis participants were randomly assigned in a 1:1 ratio to the experimental group and the control group, respectively. The study included a screening period (1 week), a double-blind treatment period (24 weeks), an exit examination (1 day), and a safety follow-up period (4 weeks). After providing informed consent, participants who met the inclusion criteria and those who did not meet the exclusion criteria were randomly assigned, in a 1:1 ratio, to receive either the trial (probiotic 6600 capsules) or the control group (placebo). The clinical remission rate (SCCAI score ≤2 and no single subscore \>1) after 24 weeks of treatment was calculated. Mayo score ≤2 and no single subscore \>1; CDAI score ≤2 and no single subscore \>1) were used as the primary efficacy index.
