Interstitial Cystitis and Dietary Interventions: A Systematic Review.
Review in International urogynecology journal, 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
introduction and hypothesisInterstitial cystitis/bladder pain syndrome (IC/BPS) is prevalent and disrupts daily life. Dietary modification is commonly recommended, but evidence is fragmented. We systematically compared dietary interventions; we hypothesized that individualized elimination may improve symptoms, but overall randomized evidence remains limited.
methodsWe searched PubMed, EMBASE, Cochrane, Web of Science, and Scopus from inception through March 2025. Primary outcomes used validated symptom scales (Genitourinary Pain Index [GUPI], O'Leary-Sant Symptom/Problem Index [OSSI/OSPI], and visual analog scale [VAS]). Hedges' g with 95% confidence intervals (CIs) were extracted or calculated for each comparison (N = 147 participants). Owing to heterogeneity, we conducted a structured narrative synthesis.
resultsFour studies with 147 patients were included. Elimination diet significantly reduced the OSSI (g = -0.89, 95% CI -1.61, -0.16) and OSPI (g = -1.97, 95% CI -2.80, -1.15) at 12 months, and showed significant improvements in pain. Anti-inflammatory diet showed no significant differences (g = -0.16, 95% CI -1.04, 0.72 to g = -0.40, 95% CI -1.29, 0.49) on RAND Interstitial Cystitis Epidemiology and GUPI scores. E-health-supported dietary coaching moderately improved VAS Pain (g = -0.96, 95% CI -1.46, -0.45) and urgency (g = -0.68, 95% CI -1.18, -0.19). Hydrogen-rich water showed nonsignificant effects across all outcomes.
conclusionsIndividualized elimination may offer symptom benefit, whereas anti-inflammatory patterns and hydrogen-rich water showed no clear advantage in small, short-term trials. Current randomized evidence is insufficient to support strong recommendations; adequately powered RCTs (≥ 6-12 months) are needed.
