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
Background: Several studies have suggested that high intakes of legumes and soy products are associated with a lower risk of hypertension; however, the results have been inconsistent. We conducted a systematic review and meta-analysis to clarify the association between legumes and soy consumption and the risk of hypertension. Methods: PubMed and Embase databases were searched up to 14 June 2025. Random effects models were used to calculate summary relative risks (RRs) and 95% confidence intervals (95% CIs) for the association between legume or soy consumption and hypertension risk. Heterogeneity was evaluated using I Results: 12 prospective studies were included in the meta-analysis. The summary RR for high versus low intake of legumes was 0.84 (95% CI 0.77 to 0.93, I Conclusion: In this meta-analysis of 12 prospective cohort studies, legume and soy intakes were associated with lower risk of hypertension. These findings support dietary recommendations to increase the intake of legumes in the general population.
