Overview of subjective cognitive decline in Brazil: a narrative review.
Review in Dementia & neuropsychologia, 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
Subjective cognitive decline (SCD) is characterized by the individual's self-perception of cognitive decline, without functional impairment and objective confirmation through neuropsychological testing. SCD has been studied as a possible clinical marker of early stages of neurodegenerative diseases, especially Alzheimer's disease. This article presents a narrative review of the available literature on the context of SCD in Brazil, covering conceptual aspects, diagnosis, etiologies, assessment measures used in the country, case outcomes, epidemiological data, and predictors of progression. Proposals for the evaluation and clinical monitoring of patients with SCD were also developed. Although there is growing scientific interest in the topic, gaps remain in the clinical approach to SCD, and a lack of national data and specific tools validated for the Brazilian population persists.
