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.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
