Legume intake on gut microbiome and glycemia in type 2 diabetes management: narrative review.
Review in Frontiers in nutrition, 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
Legumes are rich in dietary fiber, plant proteins, micronutrients, and bioactive compounds, offering a sustainable and affordable addition to the diet. However, the extent to which legume-induced modulation of the gut microbiota contributes to glycemic regulation in type 2 diabetes (T2D), relative to microbiota-independent physiological mechanisms, remains insufficiently defined. This narrative review synthesizes current evidence on legume-based interventions and their effects on gut microbiota composition and function in relation to glycemic control. Relevant studies were identified through structured searches of MEDLINE and the Cochrane Central Register of Controlled Trials via Ovid, complemented by manual screening of reference lists. Seventeen studies (three human and 14 animal trials) were considered in this review. Human studies report that consuming legumes is associated with improved glucose tolerance and blood glucose levels, although effects on microbiota composition are variable and modest. Conversely, animal studies demonstrate improvements in insulin sensitivity, glucose tolerance, and microbial diversity with higher dose legume interventions. Legume consumption has been associated with enrichment of beneficial microbial taxa, such as
