Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The variables to be evaluated are the level of H2 over time, symptoms (bloating, abdominal pain and bloating) and diarrhea. Using Lilliefors tests, parametric tests, confidence intervals of 90% in market of normality of variables. In the case of non-normal non-parametric tests for group averages will be realized. For comparisons of means between two groups, Student t test (for parametric) or Mann-Whitney test (for non-parametric) will be realized. | — |
