Development and validation of a predictive model to forecast the cerebrovascular risk burden in older people using the NACC and ROSMAP dataset.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionThe integrity of the brain's vascular system is vital for neuronal health. Cerebrovascular microbleeds, microinfarcts, and infarcts (defined as cerebrovascular disease burden) contribute to stroke and cognitive impairment. Here, we developed and validated the first model, the Cerebrovascular Disease Burden Risk Score (CDBRS) for individualized risk prediction.
methodsLeveraging the AutoScore and AutoScore-Ordinal algorithms, the CDBRS was developed using National Alzheimer's Coordinating Center (NACC) data and externally validated on Religious Orders Study and Memory and Aging Project (ROSMAP) data. The CDBRS was evaluated using mean area under the receiver operating characteristic curve (mAUC), Harrell's generalized c-index, sensitivity, and specificity.
resultsThe CDBRS achieved a promising predictive performance and outperformed the respective baseline models. The performance of the CDBRS remains good on external validation. DISCUSSION: CDBRS can possibly aid in identifying individuals with high risks of cerebrovascular microbleeds, microinfarcts, and infarcts, to enable closer monitoring and personalized management. Further validation of CDBRS in a diverse population is warranted. HIGHLIGHTS: Microbleeds, microinfarcts, and infarcts often precede clinical stroke and vascular dementia. We developed and validated the Cerebrovascular Disease Burden Risk Score (CDBRS), a new and interpretable model for stratifying the risk of microbleeds, microinfarcts, and infarcts in older adults. This tool developed using National Alzheimer's Coordinating Center (NACC) participants data achieved promising predictive performance in Religious Orders Study and Memory and Aging Project (ROSMAP) participants. The robust predictive performance warrants its clinical validation is prospective studies.
