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
purposeA practical tool to estimate the frequency of high-Fermentable Oligo-Di-Mono-saccharides and Polyols (FODMAP) food intake in Europe is lacking. The aim of this study is to develop and validate a self-administered questionnaire evaluating high-FODMAP food consumption frequency (FFQ-FODMAP-BE) in a Belgian adult population of healthy volunteers (HV) and irritable bowel syndrome (IBS) patients.
methodsThe developed FFQ was submitted prospectively twice during two weeks to Belgian HV and IBS patients. In parallel, a food history performed by a dietician and 5-day food diaries were collected. Reproducibility was evaluated using Intra Class Correlation (ICC). Spearman and Kendall correlations were used to analyze associations. Sensitivity and specificity analyses and ROC have been used to determine a threshold of the FFQ-FODMAP-BE score.
resultsSixty-four participants were included (32 HV, 32 IBS patients; 73% female). Mean daily total FODMAP intake was 11.9 (6.2) grams. The ICC showed a good agreement between the two FFQ-FODMAP-BE scores (ICC = 0.86, 95%CI [0.78-0.91]). A correlation was observed between FFQ-FODMAP-BE score and the dietician score (Spearman rho = 0.33, 95%CI [0.10-0.56]) (Kendall Tau-b = 0.25, 95% CI [0.07-0.43]) and also with average daily FODMAP consumption (Spearman rho = 0.36, 95%CI [0.06-0.66]) (Kendall Tau-b = 0.26, 95% CI [0.05-0.46]). Using a threshold of 1.80, the FFQ-FODMAP-BE has a sensitivity of 80% and specificity of 73% to discriminate low (< 9g/d) from moderate/high consumers (≥ 16g/d) (J = 0.53).
conclusionThe FFQ-FODMAP-BE questionnaire is reproducible and correlated to the subjective assessment by expert dieticians. This tool may help to identify moderate/high-FODMAP consumers.
