1 · What the graph read from 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.

2 · The registry

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

backgroundHealthy diets have been associated with better cognitive function. Socioeconomic factors including education, poverty, and job complexity may modify the relationship between diet and cognition.

methodsWe used adjusted linear mixed models to examine the association between long-term adherence to the Mediterranean-Dietary Approaches to Stop Hypertension - Intervention for Neurodegenerative Delay (MIND) diet and cognitive function over 8 years of follow-up in Puerto Rican adults residing in the Boston, MA area (aged 45-75 years at baseline). We also examined whether the MIND diet-cognition association was confounded or modified by socioeconomic measures.

resultsIn both cross-sectional and longitudinal analyses the highest, versus lowest, MIND quintile was associated with better cognition function (β = 0.093; 95% CI: 0.035, 0.152; p trend = .0019), but not with cognitive trajectory over 8 years. Education <=8th grade (β = -0.339; 95% CI: 0.394, -0.286; p < .0001) and income-to-poverty ratio <120% (β = -0.049; 95% CI: -0.092, -0.007; p = .024) were significantly associated with lower cognitive function, while higher job complexity (β = 0.008; 95% CI: 0.006, 0.011; p < .0001) was associated with better cognition function. These variables acted as confounders, but not effect modifiers of the MIND-diet-cognitive function relationship.

conclusionAdherence to the MIND diet was associated with better cognitive function at baseline and over 8 years of follow-up; however, MIND diet was not associated with 8-year cognitive trajectory. More studies are needed to better understand whether the MIND diet is protective against long-term cognitive decline.
