All the statistical analysis was performed by STATA Software version 16.0. The GSRS Indigestion subscale score, global evaluation of patient scores, and other cumulative subscale scores in the GSRS questionnaire were represented as continuous variables.
A comparative analysis was performed for normally distributed data within the group, and the results were presented as mean, standard deviation/standard error, and P value. For nonnormally distributed data within the comparative group, analysis was performed using the Wilcoxon Signed-Rank test. The results were presented as median, range, and P value. An unpaired t test/Mann-Whitney test was performed for the comparative analysis between treatment groups. The level of statistical significance for each test is defined as P < .05. Other secondary endpoints, Bristol stool analysis, brain fog questionnaire, and the occurrence of adverse events, were presented as categorical variables. A descriptive comparison was provided to differentiate the treatment effects between the treatment groups and within treatment groups.
