Interest of body composition assessment in the accuracy of the diagnosis of undernutrition in the older population in Senegal: A cross-sectional and prospective study.
Article in JAR life, 2025. 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
Introduction: In the absence of consensus on the diagnostic criteria for undernutrition in the elderly, there is a significant number of missing cases of disease in this target, particularly in areas with limited resources, including Senegal. We wanted to contribute to a better diagnostic approach to undernutrition in the elderly, by determining the relevance of body composition assessment using BIA. Design: Cross-sectional and prospective study. Setting and Participants: Individuals aged ≥ 60 years old, attending outpatient consultations at Fann University Hospital and the Retirement Provident health Center (IPRES), who were able to stand for 3 min without technical and/or human assistance were included. Methods: We used the Mini Nutritional Assessment (MNA) and Body Mass Index (BMI) to determine the prevalence of undernutrition and a Tanita BC 601® brand body composition monitor to assess body composition. Data were analyzed using SPSS version 29.0. Results: We included 73 individuals with a mean age of 72.48 ± 7.23 years old, predominantly male, with a sex ratio of 1.43. Undernutrition, the main geriatric syndrome, affected 46.6 % of the study subjects according to the MNA and/or BMI, including two- thirds in men. The mean lean mass index was 16.07 ± 3.03 kg/m² in men and 15.53 ± 2.51 kg/m² in women. It was significantly lower in cases of malnutrition, with an average of 14.38 ± 2.82 kg/m² among malnourished elderly individuals. Conclusion: Malnutrition in the elderly is best assessed early by a combination of diagnostic tools including MNA, BMI and lean mass index assessed by BIA.
