Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Chemotherapy + Standard Dose Vitamin D | FOLFOX-bevacizumab: intravenously on Day 1 (+/- 7 days) of every two-week cycle per institutional standards + 400 IU vitamin D3 orally once daily~Participants were treated until disease progression, unacceptable toxicity or withdrawal for other reasons. | 54 | 67 | EG000 |
| Group 2 | Chemotherapy + Higher Dose Vitamin D | FOLFOX-bevacizumab: intravenously on Day 1 (+/- 7 days) of every two-week cycle per institutional standards + 8000 IU daily x 2 weeks as loading dose, followed by 4000 IU daily as maintenance dose.~Participants were treated until disease progression, unacceptable toxicity or withdrawal for other reasons. | 45 | 68 | EG001 |
