Effect of dietary patterns on functional dyspepsia in adults: a systematic review.
Synthesis in Journal of health, population, and nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectivesDietary patterns may play important roles in functional dyspepsia (FD) which is one of the widely prevalent functional gastrointestinal disorders (FGID)s. This systematic review aimed to investigate the effect of various dietary patterns on FD in adults.
methodsWe searched Embase, Medline (accessed via PubMed), Web of Science (WoS), Scopus, and Cochrane from inception to March 2025. Eligible studies included randomized clinical trials and observational studies enrolling adults (≥ 18 years old). We assessed the risk of bias and evaluated the quality of evidence using the GRADE approach.
resultsSeven studies (three RCTs and four cross-sectional studies) were included. Moderate-quality evidence suggests that a protein-rich DASH diet (Absolute risk (AR):140 more, 95%CI: 58 to 252 more in 1,000) and an unsaturated fat-rich DASH diet (AR: 113 more, 95%CI: 31 to 227 more in 1,000), compared to baseline diet, are likely to increase Postprandial Distress Syndrome (PDS). Moderate-quality evidence indicates that high versus low adherence to the Mediterranean diet (MD), a diet rich in fibers, mono- and polyunsaturated fatty acids, antioxidants, and polyphenols, reduced the likelihood of FD (AR:151 fewer, 95%CI: 74 to 203 fewer in 1,000). It is uncertain whether vegetarian and vegan diets, compared to a usual diet, affect PDS due to the very low quality of evidence.
conclusionRigorously conducted RCTs and observational studies are needed to establish the association between dietary patterns and functional dyspepsia.
