1 · What the graph read from 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.

2 · The registry

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

Background: Diet influences gut microbiota-derived metabolites, which may affect vascular inflammation and calcification. The Dietary Index for Gut Microbiota (DI-GM) captures dietary patterns hypothesized to support favorable microbial metabolite profiles. In this study, we examined whether higher DI-GM scores are associated with lower carotid calcification burden in ischemic stroke patients and whether trimethylamine N-oxide (TMAO) is statistically associated with this relationship, without implying causality. Method: In this cross-sectional study of 788 ischemic stroke patients from Central Hospital Affiliated to Shandong First Medical University, we calculated DI-GM scores from validated food frequency questionnaires and quantified carotid calcification using the Agatston method via computed tomography angiography. Plasma TMAO levels were measured by enzyme-linked immunosorbent assay (ELISA) ELISA. Results: Our findings revealed that participants in the highest DI-GM tertile had significantly lower calcification scores (76.07 ± 14.55) compared to the lowest tertile (316.00 ± 75.33, Conclusion: Higher DI-GM score is cross-sectionally associated with lower carotid calcification and TMAO-mediated pathways, but causality remains unproven without longitudinal and microbiome-sequencing data.
