Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Magnesium Oxide | Magnesium oxide capsules 800mg twice daily (total of 1000mg of elemental magnesium) for year 1. Upon completion of the first year, barring any safety concerns, all subjects were administered 2500 mg magnesium oxide (total of 1500 mg elemental magnesium) daily for up to one additional year. Subjects received 600 mg elemental magnesium oxide in the morning (taken as two 500 mg magnesium oxide capsules, each containing 300 mg elemental magnesium) and 900 mg elemental magnesium oxide in the evening (taken as three 500 mg magnesium oxide capsules, each containing 300 mg elemental magnesium). | 0 | 22 | EG000 |
| Group 2 | Placebo | Placebo year 1. Upon completion of the first year, barring any safety concerns, all subjects were administered 2500 mg magnesium oxide (total of 1500 mg elemental magnesium) daily for up to one additional year. Subjects received 600 mg elemental magnesium oxide in the morning (taken as two 500 mg magnesium oxide capsules, each containing 300 mg elemental magnesium) and 900 mg elemental magnesium oxide in the evening (taken as three 500 mg magnesium oxide capsules, each containing 300 mg elemental magnesium). | 0 | 22 | EG001 |
