Racial/Ethnic Differences in Neuropsychological Test Performance in Frontotemporal Degeneration.
Article in medRxiv : the preprint server for health sciences, 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
backgroundRacial and/or ethnic differences in neuropsychological test performance are understudied in frontotemporal degeneration (FTD) but their identification is critical to identifying ways to improve care of representative FTD populations.
methodsDifferences in cognitive scores between Black and Hispanic relative to White participants were assessed with the sequential addition of potential contributing factors. Group differences in the likelihood of impairment status in cognitive test performance were also evaluated.
resultsMinoritized individuals had lower scores and/or greater likelihood of impairment on measures of lexical retrieval, processing speed, cognitive flexibility, and working memory but not global cognition, verbal recall, attention, and category fluency. Addition of factors attenuated group differences. DISCUSSION: Racial/ethnic differences on neuropsychological tests used in diagnosis and monitoring of FTD were substantially attenuated when accounting for potential contributing factors. To address these differences in FTD, future efforts must increase representative research participation of patients and understand social determinants of health.
