What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in stool quality
Time Frame: 30 days
Stool consistency (using the Bristol Stool Scale) from baseline to day 30. The Bristol Stool Scale is a tool to assess gut health by classifying feces into seven categories based on shape and consistency: types 1-2 indicate constipation, 3-4 are normal, and 5-7 suggest diarrhea.
