PLAIN-LANGUAGE SUMMARY
What it found
The overall HbA1c estimate was −0.30 percentage points (95% confidence interval: −0.63 to 0.02), which did not establish a clear difference. Fasting glucose was modestly lower.
Keep these limits in view
Small, short studies leave uncertainty. Subgroup findings should not replace the overall estimate or be treated as evidence of diabetes prevention.
