The Impact of Macronutrient Ordering on Postprandial Glycaemic Control in Diabetes: A Systematic Review.
Synthesis in Endocrinology, diabetes & metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsThis systematic review aims to investigate if macronutrient ordering is effective at lowering postprandial glucose excursions in individuals with diabetes.
methodsA systematic search of Medline, Embase and Web of Science was conducted up to February 2025. Two independent reviewers screened title and abstract using Covidence software. Data extraction and risk of bias assessment were performed by one reviewer and checked by a second reviewer. Findings were synthesized narratively. PROSPERO registration: CRD42025639742.
resultsIn total, we included six studies involving 144 participants. Most studies reported that a carbohydrate last meal pattern was effective at lowering postprandial glucose excursions in individuals with diabetes. There was some evidence for the carbohydrate last meal pattern lowering insulin levels and increasing GLP-1 and GIP levels in individuals with diabetes. The risk of bias ranged from low to some concerns, and the GRADE assessment showed a low certainty of evidence.
conclusionsEvidence suggests that the carbohydrate last meal pattern effectively reduces postprandial glucose excursions in individuals with diabetes. However, significant heterogeneity in study design limits overall certainty in the findings. Further research is needed to confirm these effects.
