Exploring Language Impairment in Catalan-Dominant Bilinguals with Primary Progressive Aphasia: Preliminary Data.
Article in Brain 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
backgroundResearch on primary progressive aphasia (PPA) in minority languages and bilingual speakers remains limited, which can compromise accurate diagnosis and intervention. This is the case for Catalan, which lacks standardized tools for this population.
objectivesThis study aimed to evaluate the Catalan version of the
methodsWe administered the CAT-CAT to four participants clinically diagnosed with PPA.
resultsThe test detected participants' core linguistic impairments, such as anomia, and revealed distinct severity profiles consistent with PPA variant types. Moreover, it captured deficits that were not identified by routine clinical observation or informal assessment.
conclusionsThis study provides the first detailed characterization of PPA in Catalan-speaking individuals and, although based on a small sample, its findings address a critical gap in neurodegenerative language research and highlight the importance of standardized tools to improve diagnosis and guide clinical interventions in bilingual speakers of minority languages.
