Task: Answer Verification
Input (English): Question: Does vitamin D 20,000 IU per Week for Five Years Prevent Progression From Prediabetes to Diabetes?
Answer: In subjects without vitamin D deficiency, vitamin D supplementation is unlikely to prevent progression from prediabetes to diabetes. Very large studies with inclusion of vitamin D-deficient subjects will probably be needed to show such a putative effect. This study tested if supplementation with vitamin D to subjects with prediabetes will prevent progression to type 2 diabetes (T2DM).
Output (English): no
