The association of dietary protein intake in three meals and cognitive performance among people over sixty years old.
Article in Journal of Alzheimer's disease reports. 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: Cognitive dysfunction caused by aging is becoming increasingly significant, and despite increasing global attention to the prevention and treatment of cognitive impairment, effective treatment methods remain elusive, so changing lifestyle and dietary interventions are particularly important. Objective: The aim of this study was to explore the effects of dietary protein intake on cognitive ability in the people aged over 60 years, and to provide new insights for the prevention and improvement of cognitive dysfunction in the elderly. Methods: We conducted a cross-cutting study of 2649 older adults in the National Health and Nutrition Examination Survey database between 2011 and 2014, employing weighted logistic regression analysis to investigate the relationship between protein intake at three meals and cognitive capacity. Results: In the fully adjusted model, compared to those in the lowest quantile, participants in the highest quintile of dinner protein intake had a lower risk of low cognitive performance (OR = 0.66, 95% CI 0.44-0.98 for Consortium to Establish a Registry for Alzheimer's Disease; OR = 0.64, 95% CI 0.39-0.95 for Digit Symbol Substitution Test; OR = 0.56, 95% CI 0.36-0.88 for Composite z-score). Conclusions: Our study suggests that cognitive performance may be related to dinner protein intake but not breakfast protein intake.
