Effect of Plant-Based Diets on Gut Microbiota: A Systematic Review of Interventional Studies.
Synthesis in Nutrients, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 72 papers, 2 of them syntheses that pooled it.
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
Plant-based diets have grown increasingly popular across the globe, mainly for their health and environmental benefits. Several studies have identified a link between plant-based diets and the decreased risk of developing cardiovascular diseases, obesity, and other health issues. We systematically reviewed human interventions to identify the relationship between various plant-based food items and the gut microbiome, alongside the biochemical and anthropometric measurements as secondary findings. The study selection process was completed using the COVIDENCE platform. Overall, 203 studies were identified, of which 101 were chosen for title and abstract screening by two independent authors. Following this process, 78 studies were excluded, and the full texts and the reference lists of the remaining 23 records were reviewed using the review eligibility criteria. A manual search yielded five additional articles. In the end, 12 studies were included in the systematic review. We found evidence for short- to moderate-term beneficial effects of plant-based diets versus conventional diets (duration ≤ 13 months) on gut microbiome composition and biochemical and anthropometric measurements in healthy participants as well as obese, cardiovascular, and rheumatoid arthritis patients. However, contradictory results were observed for Enterobacteriaceae, at the family level, and for Faecalibacterium and Coprococcus, at the genus level, of gut microbiome composition. The relationship between plant-based diets and the gut microbiome, alongside their underlying metabolic and inflammatory effects, remains largely unexplored. Hence more interventional studies are needed to address these questions.
