Investigating the utility of sarcopenia associated SARC-F and MSRA questionnaires in identifying falls and self-reported functional impairment in juvenile idiopathic arthritis.

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
introductionChronic inflammation associated with ageing contributes to sarcopenia-related risk of falls and multimorbidity. The SARC-F questionnaire, based on strength, ambulation, rising from a chair, climbing stairs and falling, and MSRA (mini sarcopenia risk assessment) are validated tools to identify sarcopenia in elderly people. Here, we investigated whether SARC-F and MSRA questionnaires capture higher rates of self-reported functional difficulties and falls in young individuals living with juvenile idiopathic arthritis (JIA).
methodsJIA patients and healthy participants were invited to complete an online survey including the SARC-F, MSRA-5, and MSRA-7 questionnaires. Additional questions explored their nutrition and exercise habits.
resultsWe invited 101 healthy participants and 41 patients with JIA. Of the 41 JIA respondents, the median age was 23 years and 25 (61%) were female. According to the SARC-F, MSRA-5, and MSRA-7 questionnaires, 20%, 47%, and 33% screened positive according to the respective threshold criteria. Around 27% of JIA patients reported at least one fall in the past year compared to around 33% of healthy participants. However, 20% of JIA participants reported more than four falls in the past year in contrast to 4% of healthy participants. Furthermore, 44% of JIA participants reported difficulty climbing stairs and 17% reported limited ability to walk one kilometer.
conclusionsSARC-F identified a higher proportion of young adults with JIA reporting functional difficulties and recurrent falls compared with healthy controls. MSRA-5 showed differences in some risk-factor domains. However, without validation against objective measures of muscle mass, strength, or performance, these questionnaires primarily reflect multifactorial JIA-related musculoskeletal impairment rather than sarcopenia per se. Further studies with gold-standard sarcopenia assessments are needed.
