There was no overall pooled effect on HbA1c in favor of restricting carbohydrate.
Carbohydrate restriction may not significantly improve glycaemic control in Type 2 diabetes.
StrongRefutesmedium confidence
The pooled effect estimate from meta‐analysis was a weighted mean difference of –0.09% [95% CI –0.27, 0.08 ( P = 0.30); I 2 72% ( P <0.001)], suggesting no effect on HbA 1c of restricting the quantity of carbohydrate.
Why this rating
Based on a systematic review and meta-analysis of randomized controlled trials.
