Assocation Between a Brain Care Score Derived from Participant Responses and Incident Stroke from the COSMOS Study.
Article in American journal of lifestyle medicine, 2025. 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
objectiveThe Brain Care Score (BCS), previously validated to predict the risk of age-related brain diseases, incorporates 12 modifiable risk factors, including blood pressure and laboratory measurements. In the U.S., fewer than 50% of individuals recall these measurements, limiting the BCS's accessibility. This study aims to evaluate the predictive validity and discriminatory power of a BCS derived from participant responses for incident stroke.
methodsWe performed retrospective analyses using the prospectively collected COSMOS data. The BCS, ranging 0-19 points, was calculated from modifiable risk factors derived from participant responses only. A Cox proportional hazard model, adjusted for sex and age was used to estimate the association between a higher BCS, indicating better brain health, and incident stroke.
resultsAmong 17 150 participants (median age 70.8, 59.6% female) free of stroke and TIA at baseline and with complete BCS data, 187 (1.1%) experienced a stroke during a mean follow-up duration of 3.6 (SD:0.7) years. A 5-point higher BCS was associated with a 36% lower stroke risk (HR:0.64 [95%CI:0.48-0.84], c-statistic:0.68). DISCUSSION: A BCS derived from participant responses showed similar predictive performance and discriminatory ability compared to previous validation studies that use physical and laboratory measurements. Future studies could consider incorporating the BCS derived from participant responses when physical and laboratory measurements are not readily available.
