Clinical Correlation and Metabolic Findings on 18F-Fluorodeoxyglucose Brain PET in Dementia With Lewy Bodies: A Case Report.
Article in Cureus, 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
Neurodegenerative dementias comprise a heterogeneous group of diseases with distinct pathological substrates, among which Alzheimer's disease, dementia with Lewy bodies (DLB), and frontotemporal dementia are the most prominent. The early and accurate diagnosis of these conditions remains a clinical challenge, in which both structural and functional imaging techniques play crucial roles. This article presents a case of a 68-year-old female patient with progressive cognitive decline, evaluated using ¹⁸F-fluorodeoxyglucose positron emission tomography (¹⁸F-FDG PET), which revealed a characteristic pattern of symmetric hypometabolism in the temporal, parietal, and occipital lobes, with preserved metabolism in the posterior cingulate cortex (the cingulate island sign), a finding highly suggestive of DLB. This case highlights the value of ¹⁸F-FDG PET as a diagnostic tool in the differential evaluation of dementias and underscores the importance of recognizing the specific metabolic pattern of DLB to support timely clinical decision-making. The model incorporating visual and semi-quantitative parameters achieved a diagnostic accuracy of 84.3%.
