Decoding dietary pectin: from structural complexity and microbial CAZyme-PUL networks to cross-feeding and host-beneficial metabolites.
Review in Gut microbes, 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
The interaction of pectin, as one of the most complex dietary glycans, with gut microbiota represents a typical pattern for shaping the gut microenvironment and human homeostasis. Pectin has a heterogeneous structure, characterized by homogalacturonan (HG), rhamnogalacturonan I (RG-I), and rhamnogalacturonan II (RG-II) domains, which dictate its fermentability and functional outcomes. This review systematically examines the pathways through which pectin is degraded by the gut microbial consortia, with a central focus on the role of carbohydrate-active enzymes (CAZymes). These enzymes, including glycoside hydrolases (GHs), polysaccharide lyases (PLs), and carbohydrate esterases (CEs), act synergistically to depolymerize pectin into oligosaccharides and monosaccharides.
