Effect of Exercise Versus Metformin among Nigerians with Prediabetes: A Randomised Controlled Trial.

Among Nigerians with prediabetes, moderate exercise, and metformin interventions have significantly higher efficacy than placebo in improving glucose tolerance. However, moderate exercise and metformin have comparable efficacy in improving glucose tolerance and diabetes risk reduction. Participants in this study need to be followed up for a longer period to assess the long-term effects of these interventions.
