Figure 1. Assessment of the change in BMD over time in patients with type 2 diabetes on metformin alone compared to control. (A) Overall average BMD was not significantly different over time in the metformin alone versus control group (P = 0.747). (B) Comparison of BMD at the right and left femur shows improvement in the metformin alone group compared to control over time (right femur P = 0.017, left femur P = 0.130).
