Nutrition Knowledge and Food Literacy Among Persons with Multiple Sclerosis-Development and Validation of Patient-Reported Outcome Measures.
Article in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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/
objectivesPersons with MS (pwMSs) are often confronted with contradictory dietary advice, which is not always based on sound scientific evidence. This may lead to poor MS-specific nutrition knowledge (MSNK) and food literacy (MSFL). To date, no studies have assessed MSNK and MSFL among pwMSs. Moreover, no validated tools to measure the effects of educational interventions are available. The aim of this study was to develop and validate MS-specific instruments to measure MSNK and MSFL among pwMSs.
methodsBased on a validated food literacy (FL) screener for the general population and prior research about the information needs of pwMSs, we developed 14 MSFL items and 11 MS-specific nutrition knowledge questions. Cognitive debriefing was conducted with 10 pwMSs and resulted in a 12-item MS food literacy questionnaire (MSFLQ) and an 11-item MS nutrition knowledge questionnaire (MSNKQ). After refinement, both questionnaires were pilot tested in an online survey to explore their comprehensibility. The MSNKQ was analyzed descriptively (mean and percentage of correctly answered questions). For MSFLQ item difficulty, the discriminatory power of the items, internal consistency and convergent/divergent validity were assessed.
resultsIn total, 148 pwMSs (age: 47.1 years (SD = 12.5); 102 women (69%)) completed the online survey. On average, participants answered 3.51/11 MSNK questions correctly (31.9%). The MSFLQ showed good internal consistency (Cronbach's alpha = 0.85), item difficulty was good and the discriminatory power of the items was satisfactory. Correlations between the MSFLQ and a general food literacy questionnaire was high (r = 0.626,
conclusionsMSNK among pwMSs in Germany is low. The MSNKQ and MSFLQ appear to be suitable instruments to assess MSNK and MSFL and might serve as outcome measures for educational interventions.
