Development and validation of the FR-QoL-29-Dutch (Flemish) Questionnaire and assessment of clinical factors associated with food-related quality of life in a Belgian inflammatory bowel disease population: a cross-sectional study.

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
objectiveFood-related quality of life (FR-QoL) is the psychosocial impact of food, nutrition, eating and drinking on QoL and can be profoundly affected by inflammatory bowel disease (IBD). We aimed to translate and validate the FR-QoL-29 Questionnaire in a Belgian IBD population and investigate associations with relevant clinical variables.
methodsThe English FR-QoL-29 was translated to Dutch using the forward-backward method. Consecutive patients with IBD attending the outpatient clinic in a university hospital in Belgium completed the FR-QoL-29 Dutch (Flemish), alongside questionnaires assessing disease severity and IBD-related disability. Clinical and biochemical data were collected. Exploratory factor analysis (EFA) with promax rotation assessed the underlying factor structure. Reliability measures (internal consistency, test-retest reliability) were evaluated. Pearson and Spearman correlations assessed relationships between FR-QoL-29 Score and continuous demographic and clinical variables, while categorical parameters were analysed using independent t-tests and one-way analysis of variance with Tukey post hoc tests.
results301 patients were included, with 31 (10.3%) completing the retest. EFA revealed a one-factor structure explaining 55% of the variance. The FR-QoL-29-Dutch (Flemish) showed excellent internal consistency (Cronbach's α=0.97) and very good test-retest reliability (intraclass correlation=0.94). Lower FR-QoL-29 Score was associated with higher serum albumin levels, younger age, disease activity and IBD-related disability. FR-QoL-29 Score was lower in females, those with Crohn's disease (CD), CD patients with a stricturing phenotype and those previously receiving IBD-related surgery.
conclusionThe FR-QoL-29-Dutch (Flemish) is valid and reliable and correlates with disease activity and IBD-related disability. Patients with CD, stricturing disease and who previously underwent IBD-related surgery have a significantly lower FR-QoL and should be targeted for support.
