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

introductionBiological, genetic, and sociocultural factors underlying cognitive resilience and resistance to pathology remain unexplored in Latin America. The Life-Course Epidemiology of Aging, Resilience, and Neurodegeneration in Alzheimer's Disease (LEARN-AD) study and Latin American SuperAgers Study (LASAS) establish the first harmonized frameworks to characterize resilience and exceptional cognitive aging phenotypes in the region.

methodsThe shared protocol integrates cognitive, neurological, psychosocial, and genetic data. SuperAgers are deeply phenotyped, while successful cognitive agers are identified through harmonized criteria applied to existing cohorts, ensuring regional adaptation and international comparability. Centralized training and shared procedures ensure cross-site consistency.

resultsWe define eligibility criteria and standardized assessments to classify successful cognitive agers and SuperAgers in Latin America and examine biological and psychosocial profiles supporting better-than-expected cognition. DISCUSSION: LEARN-AD and LASAS represent the first Latin American infrastructure for studying cognitive resilience, resistance, and exceptional cognitive aging, which will generate unprecedented regional databases and grow into larger networks, providing foundations for research, prevention strategies, and precision approaches to promote brain health in Latin America.
