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

Background: As populations age globally, identifying modifiable dietary factors to support cognitive health has become a pressing research and public health priority. While specific nutrients have been linked to cognitive outcomes, few studies have explored the associations between habitual food group consumption on specific cognitive domains using standardized screening tools. Methods: To investigate associations between dietary habits, relate to distinct cognitive domains in older adults by analyzing the food consumption in relation to memory, verbal fluency, and global mental status. Spearman correlation coefficients were employed to evaluate associations. Results: Several nutrient-dense foods, such as nuts, extra virgin olive oil (EVOO), dark chocolate, and eggs, were linked to improved memory and verbal fluency. Conversely, higher intake of dairy products, refined grains, sugary products and red meat correlated with lower cognitive performance, particularly in verbal fluency. A higher proportion of saturated and trans fats, and proteins was inversely associated with cognition, while total fat and monounsaturated fatty acids (MUFA) intake showed positive associations, consistent with the protective role of EVOO. Conclusion: This study identifies specific, commonly consumed foods that correlate with cognitive function in aging adults. Given the cross-sectional design, associations should not be interpreted as causal, but they underscore the potential of food-based dietary strategies, rather than nutrients specific interventions, to preserve cognitive health and potentially delay age-related cognitive decline.
