Sarcopenia association with physical and psychological indices in community-dwelling aged population, Birjand Longitudinal Aging Study (BLAS).

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
backgroundSarcopenia is a progressive syndrome associated with adverse outcomes in older adults. This study aimed to assess the prevalence of sarcopenia and its associated risk and protective factors among community-dwelling elderly individuals.
methodsAs a part of the Birjand Longitudinal Aging Study (BLAS), this retrospective cross-sectional study assesses patients older than 60 years old. Basic characteristics, nutritional status, comorbidities, and sociodemographic data were collected. Logistic regression analyses were performed to identify factors associated with sarcopenia severity.
resultsA total of 1,348 participants (mean age: 69.73 ± 7.53 years) were classified into four groups: robust (58.85%), probable sarcopenia (31.03%), sarcopenia (4.76%), and severe sarcopenia (5.36%). On univariate analysis, being overweight or obese, any formal education, regular physical activity, and hypertension were accompanied by lower odds of sarcopenia, whereas dementia and anemia increased its odds. In the fully adjusted model, age > 70 years (OR 1.39, 95% CI 1.05-1.83) and > 80 years (OR 4.93, 95% CI 3.15-7.71), malnutrition risk (OR 1.36, 95% CI 1.02-1.82), living alone (OR 1.88, 95% CI 1.12-3.22) and dementia (OR 1.03 per 6-CIT point, 95% CI 1.01-1.05) were independent risk factors, while education lower than diploma (OR 0.63, 95% CI 0.46-0.86) and diploma (OR 0.39, 95% CI 0.22-0.67), exercise more than once per week (with different ORs regarding variable physical activity frequencies) and hypertension (OR = 0.62, 95% CI: 0.47-0.81, P-value < 0.01) were related to lower odds of sarcopenia.
conclusionsThose aged > 70, at risk of malnutrition, and having dementia had higher odds of sarcopenia. In contrast, having an educational level of a diploma or lower, ≥ one session of physical activity per week, and having hypertension showed a reverse association with sarcopenia. Findings underscore the importance of targeted interventions to mitigate sarcopenia risk in aging populations.
