Cognitive and Behavioral Functioning in Female Former Soccer Players: Results from the Head Impact and Trauma Surveillance Study (HITSS).
Article in medRxiv : the preprint server for health sciences, 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
Repetitive head impacts (RHI) from contact and collision sports have been associated with later-life cognitive and neurobehavioral impairments, as well as neurodegenerative conditions such as chronic traumatic encephalopathy (CTE). RHI-associated clinical sequelae among female former soccer players, specifically, are not well understood. This cross-sectional study aimed to examine the relationship of RHI exposure proxies (e.g., total years of soccer play, concussion history, highest level of play, and estimated cumulative heading frequency) with clinical measures (e.g., subjective cognitive complaints, objective cognitive performance, behavioral dysregulation, and depressive symptoms) among 2,732 women, aged 40 years or above, enrolled in the Head Impact and Trauma Surveillance Study (HITSS), all of whom formerly played organized soccer. HITSS participants completed an online battery that elicited self-reported cognitive and behavioral complaints and depressive symptoms, and that assessed cognitive performing via computerized tests. Multivariable linear regression models estimated associations between soccer-related RHI proxies and outcome measures, adjusting for age and education. Among the former soccer players, longer duration of soccer play, higher level of play, greater estimated cumulative heading frequency, and concussion history were significantly associated with worse self-reported cognitive functioning, greater behavioral dysregulation, and elevated depressive symptom severity. Apart from a single association between concussion history and PAL FAMS performance, we found no other associations between RHI proxies and objective cognitive test performance. Among middle-aged women who played organized soccer, cumulative RHI exposure was associated with small but statistically significant effects for measures of subjective cognitive complaints, behavioral functioning, and depressive symptoms. Continued monitoring of this large cohort of female former soccer players will improve understanding of long-term consequences of soccer play.
