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

purposeInsufficient dietary fibre intake can increase chronic disease risk with identification of effective strategies considered a public health priority. However, there are no UK-based dietary fibre intake tools to estimate consumption habits. This study addresses this gap by developing a novel dietary fibre screening tool (SCREEN-IT) for the UK population and explores validity, reproducibility and usability insights.

methodsSCREEN-IT was developed based on key dietary fibre-rich food categories in the UK diet. The validity of SCREEN-IT (10-item) was tested against a UK-based Food Frequency Questionnaire (eNutri-FFQ; 157-item) seven-days apart (n = 70; 55.1 ± 18.7 years). SCREEN-IT reproducibility (n = 155; 51.7 ± 18.2 years) was evaluated on two occasions (four-weeks apart) and usability (System Usability Scale; SUS) was assessed. Intra-class correlation coefficients, percentage difference, quartile agreement, weighted kappa and Bland-Altman plots were used to quantify agreement and extent of bias.

resultsAgreement between methods (SCREEN-IT vs. eNutri-FFQ) was "acceptable to good agreement"; higher dietary fibre estimates from eNutri-FFQ (mean bias: -3.91 g/d). SCREEN-IT was quick to complete (< 5-min) with higher SUS than eNutri-FFQ (83.4 vs. 76.8/100). SCREEN-IT was reproducible on re-test ("acceptable to good agreement"), mean bias close to zero (-0.04 g/d), high usability (84.9/100) and received positive feedback (easy-to-use, functional, thought-provoking, enjoyable).

conclusionSCREEN-IT was successfully developed with favourable validity, reproducibility and usability feedback. It was considered a suitable tool to estimate dietary fibre intake for the UK population. This novel tool could help raise dietary fibre awareness by promoting relevant food sources in a quick and easy way to increase future intake.
