Cross-sectional associations between dietary intake of polyunsaturated fatty acids, physical function, and sarcopenia in community-dwelling older adults.
Article in The journal of nutrition, health & aging, 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
objectivesThe present study examined the associations between the dietary intake of polyunsaturated fatty acids (PUFAs), physical function, and the prevalence of sarcopenia in Italian community-dwelling older adults.
designCross-sectional study.
settingUnconventional settings across Italy (e.g., exhibitions, health promotion campaigns).
participantsOlder adults (65+ years) who provided a written informed consent.
methodsPhysical function was evaluated according to isometric handgrip strength (IHG) and 5-time sit-to-stand (5STS) performances. Muscle power parameters were estimated based on 5STS values. Sarcopenia was operationalized according to the presence of low physical function (IHG or 5STS) plus low appendicular skeletal muscle mass (ASM), estimated according to calf circumference. A 12-item food questionary was used to estimate the dietary intake of PUFAs, which included omega-3 (α-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid) and omega-6 fatty acids.
resultsMultiple linear regression results indicate negative and significant associations between the dietary intake of α-linolenic acid and muscle power, and between docosahexaenoic acid consumption and ASM. No significant associations were found between PUFAs-related variables and sarcopenia.
conclusionsResults of the present study indicate that PUFAs-related variables were negatively and significantly associated with physical function and body composition in older adults. Nevertheless, no significant associations were found with sarcopenia. These findings suggest that a more detailed analysis of covariates should be conducted in future investigations that aim to examine the associations between the dietary intake of PUFAs and sarcopenia-related parameters.
