Epicatechin and High-Molecular Weight Fraction Do Not Recapitulate the Antiobesity and Antidiabetes Activities of Whole Cocoa Extract.
Article in Journal of agricultural and food chemistry, 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
Cocoa flavanols show promise for inhibiting type 2 diabetes (T2D). The components responsible for this remain poorly understood. We compared cocoa extract (CE) supplementation against matched epicatechin (EC) or a high-molecular-weight fraction (HMW) in a T2D mouse model induced by high-fat (HF) plus streptozotocin (STZ). Mice were fed HF diet with STZ alone or with CE, EC, or HMW. HF + STZ animals fed CE had blunted weight gain and reduced insulin resistance compared to HF + STZ control as measured by the homeostasis model assessment of insulin resistance. However, these improvements are driven by reduced fasting glucose and insulin, as peripheral insulin resistance was not observed in the model when accounting for the fasting glucose. HF + STZ-induced dysbiosis was partially reversed by CE and HMWs. These findings demonstrate the beneficial effects of CE on the gut microbiome and cardiometabolic markers, which were not fully achieved by EC or HMW, suggesting synergistic effects of flavanols.
