Protein intake and muscle mass of community-dwelling older adults: a cross-sectional study in Kigali, Rwanda.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Older people are at high risk of protein deficiency, which accelerates the age-related loss of muscle mass. However, there is a paucity of data on the consumption of protein-rich animal-sourced foods and their relationship with dietary intake and muscle mass of older adults in low- and middle-income countries. Therefore, this study assessed ASF consumption and its associations with protein intake and muscle mass of older adults. A cross-sectional study was conducted among community-dwelling older adults in the Gasabo district, Rwanda. Dietary intake was estimated using two non-consecutive 24-h recalls. A structured questionnaire was used to collect data on socio-demographic characteristics. Inverse propensity score weighting was employed to assess the association between animal-source food (ASF) consumption and protein intake and muscle mass. Slightly more than half (56%, n = 189) of the older adults consumed ASFs. In adjusted models, ASF consumption was positively associated with protein intake (ATE: 9.6 g/d; CI, 6.8 to 12.4) and muscle mass (ATE: 1.7 kg; CI, 0.0 to 3.4). The results also showed that adding one and two or more ASFs to the diet was proportionally associated with an increase in protein intake (ATE: 4.7 g/d; 95% CI, 0.2 to 9.3 and ATE: 13.9 g/d; 95% CI, 5.9 to 22.0, respectively), but not with muscle mass (ATE: 1.2 kg; 95% CI - 1.4 to 3.9 and ATE: 1.4 kg; 95% CI - 0.6 to 9.6, respectively). The consumption of ASFs was generally low among community-dwelling older adults. However, older adults who consumed ASFs had improved protein intake and muscle mass compared with those who consumed plant-based diets. Large and prospective studies, extending beyond urban settings, are needed to identify factors that can be targeted to improve ASF consumption and overall dietary intake among older adults in Rwanda.
