SCI NutriTool: Development and Validation of a Questionnaire to Assess Non-Adherence to the Healthy Food Pyramid in Individuals with Spinal Cord Injury in Switzerland.
Article in Nutrients, 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
BACKGROUND/
objectiveRapid, validated dietary screening tools are lacking for individuals with spinal cord injury (SCI), where routine clinical check-ups do not allow sufficient time for extensive dietary assessments typically required to evaluate adherence to dietary recommendations. We developed a 15-item dietary screener (SCI NutriTool) and evaluated its accuracy in classifying non-adherence to a healthy food pyramid compared with a validated food frequency questionnaire (FFQ).
methodsThe SCI NutriTool was developed through literature review and expert consensus. In a validation study, 51 adults with SCI (mean age 57.0 years; 76.5% men; 68.8% traumatic injury) completed the SCI NutriTool twice and a validated 97-item FFQ, which served as the reference method.
resultsThe SCI NutriTool demonstrated substantial variability in performance across food groups, reflecting its domain-specific screening properties. Sensitivity was high for fruits and vegetables (91.7%), protein-rich foods (90.5%), and sweetened/alcoholic beverages and snacks (82.4%), with relatively high positive predictive values (PPV: 73.7-90.5%), supporting the tool's ability to identify individuals who are likely non-adherent and may benefit from further nutritional assessment or counselling. In contrast, for starchy foods and nuts, oils, and fatty spreads/sauces, sensitivity was low (20.0% and 50.0%), while specificity was modest. This indicates that the tool performs better in correctly identifying adherent individuals in these domains, which is reflected in higher negative predictive values (NPV: up to 94.1%). However, the low sensitivity suggests that individuals with non-adherence may be missed, limiting the tool's usefulness as an early screening trigger for these food groups.
conclusionsThe SCI NutriTool's performance varies across food groups, demonstrating a stronger ability to identify non-adherence in protein-rich foods, fruit and vegetables, sweetened and alcoholic beverages, and snacks, but limited discriminatory capacity for others. In particular, it is not suitable for screening non-adherence to starchy foods and fats. Accordingly, it is best used as a triage tool to guide further dietary assessment and targeted nutritional interventions rather than as a standalone diagnostic instrument.
