Younger Age of First Exposure to American Football Is Associated with Worse Informant-Reported Clinical Outcomes in Older Age Brain Donors.
Article in Journal of neurotrauma, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Although the younger age of first exposure (AFE) to American football has not been associated with neurodegenerative pathology, AFE has been associated with clinical symptoms. However, the literature is mixed. We examined the association between AFE to football and clinical outcomes before and after age 60 at death, to isolate the potential role of decreased neuropathological resilience in older age. This study included 677 deceased male football players who donated their brains to the Understanding Neurologic Injury and Traumatic Encephalopathy Brain Bank. Informants completed modified scales assessing cognition, function, behavior, and neuropsychiatric features with dementia adjudicated through consensus conferences. Regressions tested the association between AFE and dementia, chronic traumatic encephalopathy (CTE) pathology, and each scale, adjusted for multiple testing. Analyses were stratified by age 60, adjusting for age at death, duration of play, and neuropathology. Most donors (mean age = 60.9, standard deviation = 19.8) played college or professional football (
