Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Wait-List ControlExperimental Treatment2 Interventions
Control Group (n=100). Subjects will be told that they are in the wait-list control group. They will have a 3 month "waiting period" before they will be randomized again to a treatment group. They will be randomized to one of the previous groups.
Group II: Low Dose MetforminExperimental Treatment2 Interventions
Low Dose Metformin Group (n=100). Subjects will receive metformin and will be instructed to take 1 tab per day (1 metformin tab (500mg) for 6 months.
Group III: High Dose MetforminExperimental Treatment1 Intervention
High Dose Metformin Group (n=100). Subjects will receive metformin and will be instructed to take 2 tabs per day (1,000mg) for the first week then increase to 3 tabs per day (1,500mg) for the remaining 6 months.
Group IV: PlaceboPlacebo Group1 Intervention
Placebo Group (n=100). Subjects will receive placebo and will be instructed to take either 2 tabs per day for the first week then increase to 3 tabs per day for the remaining 6 months OR take 1 placebo tab for 6 months.

Answered by AI

What outcome is this trial looking to achieve?

"This medical trial, which will measure progress over 15 months, is looking to gauge changes from the baseline in Oswestry Disability Index. Secondary objectives involve assessing variance from initial scores on three other scales: McGill Pain Questionnaire (0-45; higher score indicates more pain), Connor-Davidson Resilience Scale 25 (0-100; greater resilience indicated by a higher score) and Catastrophizing Scale (0-36; with a high number indicating increased levels of catastrophizing)."
