Article in The journals of gerontology. Series A, Biological sciences and medical sciences, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00672685 (Assessment of the Efficacy of Omega-3 Fatty Acids Supplementation, Multi-domain Intervention or Their Combination on the Change of Cognitive Functions in Frail Elderly Subjects), which is not on this map.

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.

Abstract
There is growing evidence that cognitive decline can be affected by both nutritional aspects and inflammation. Plasma neurodegenerative biomarkers stand out as minimally invasive useful measures to monitor the potential risk of cognitive decline. This study aimed to investigate the associations between biomarkers of neurodegeneration, nutrition, and inflammation among community-dwelling older adults, and to verify if associations differed according to apolipoprotein E (APOE) ε4 status. This cross-sectional analysis included 475 participants ≥70 years old from the Multidomain Alzheimer Preventive Trial (MAPT), mean age 76.8 years (SD = 4.5), 59.4% women. Biomarkers of neurodegeneration (plasma amyloid-β 42/40-Aβ 42/40, neurofilament light chain-NfL, progranulin), nutrition (erythrocyte docosahexaenoic acid, eicosapentaenoic acid, omega-3 index; plasma homocysteine-Hcy, 25 hydroxyvitamin D), inflammation (plasma tumor necrosis factor receptor 1-TNFR-1, monocyte chemoattractant protein 1-MCP-1, interleukin 6-IL-6), and cellular stress (plasma growth differentiation factor 15-GDF-15) were assessed. Linear regression analyses were performed to investigate the associations between nutritional and inflammatory biomarkers (independent variables) and neurodegenerative biomarkers (dependent variables), with adjustments for age, sex, education, body mass index, physical activity, allocation to MAPT groups, and APOE ε4 status. After adjusting for confounders, Aβ 42/40 was not associated with nutritional or inflammatory markers. NfL was positively associated with GDF-15, TNFR-1, IL-6, and Hcy. Progranulin was positively associated with GDF-15, TNFR-1, and MCP-1. Analyses restricted to APOE ε4 carriers (n = 116; 26.9%) or noncarriers were mostly similar. Our cross-sectional study with community-dwelling older adults corroborates previous evidence that inflammatory pathways are associated to plasma markers of neurodegeneration.
