Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sulforaphane | Participants will take a sulforaphane supplement 3-8 tablets daily, with dose depending upon body weight. Each tablet contains 125 mg broccoli seed powder and 50 mg broccoli sprout extract, providing approximately 15 µmol sulforaphane.~The weight-based dosing schedule is as follows:~3 tablets (approx. 46.5 µmol SF) if \<100 lb; 5 tablets (approx. 77.5 µmol SF) if 100-125 lb; 6 tablets (approx. 93 µmol SF) if 126-175 lb; 7 tablets (approx. 108.5 µmol SF) if 176-199 lb; 8 tablets (approx. 124 µmol SF) if ≥ 200 lb | 0 | 24 | EG000 |
| Group 2 | Placebo | Participants in this arm will take placebo tablets that are identical in shape, size, and color to the sulforaphane tablets. The number of tablets taken per day corresponds to the weight-based schedule described for the sulforaphane arm. | 0 | 24 | EG001 |
