Association between dietary animal-derived branched-chain amino acids and sarcopenia in older adults: a cross-sectional study based on Chinese community.
Article in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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: The free-living dietary intake of branched-chain amino acids (BCAAs, including leucine, isoleucine, and valine) may have an impact on sarcopenia. This study aimed to compare the dietary BCAAs of animal sources related to sarcopenia in older individuals aged ≥ 55 years living in Chinese communities. Methods: We enrolled 367 older individuals (112 males and 255 females) aged over 55 years in six communities. Sarcopenia was diagnosed based on Asian Working Group for Sarcopenia (AWGS2019). The free-living dietary intake of BCAAs was evaluated by using a 64-item food frequency questionnaire (FFQ). Multivariable logistic regression models were applied to examine the association between BCAAs and sarcopenia. Results: The overall prevalence of sarcopenia was 20.7% (76 in 367). The mean daily energy intake, protein, fat, and BCAAs were significantly lower in the sarcopenia older adults than in the non-sarcopenia group ( Conclusion: High intake of dietary BCAAs was strongly associated with lower risk of sarcopenia in older adults. Animal-derived BCAAs intake may decrease the risk of sarcopenia in older adults, whereas no such effect was observed for plant-derived BCAAs.
