Histidine-Containing Dipeptides in Obesity and Cardiometabolic Health: A Systematic Scoping Review.
Article in Obesity reviews : an official journal of the International Association for the Study of Obesity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundHistidine-containing dipeptides (HCDs) have been reported to have anti-inflammatory and antidiabetic properties. Yet, no previous reviews have examined the impact of HCDs on Type 2 diabetes (T2D) risk factors (e.g., obesity) and progression (e.g., microvascular and macrovascular complications). In this scoping review, we aimed to thoroughly examine the evidence on the effects of HCDs, particularly carnosine, which is the most studied HCD, on T2D risk factors and complications and the underlying mechanisms of action.
methodsWe systematically searched Ovid-Medline, Embase, CINAHL, Scopus, Web of Science, and Cochrane Library from inception to December 2023. We included experimental studies (animal models and cell studies), observational studies, and randomized controlled trials (RCTs) investigating the mechanism of action of HCDs and the effects of supplementation in individuals with obesity and/or T2D.
resultsThe primary literature search yielded 10,973 articles and 121 studies were eligible for inclusion. HCDs have been shown to mitigate inflammation and improve lipid profile and glycemic control in obesity and T2D with or without microvascular and macrovascular complications. However, most studies are experimental, focusing on elucidating the potential mechanisms of action of HCDs, with limited observational data or RCTs of individuals with obesity and/or T2D. No RCTs have investigated the effects of HCDs in individuals with neuropathy, retinopathy, cerebrovascular disease, and cardiovascular disease within a diabetic context.
conclusionsAlthough the existing evidence, predominantly from preclinical studies, generally supports the use of HCDs for improving cardiometabolic health, further human studies, especially RCTs with adequately powered sample sizes, are needed.
