Effect of genetic factors on [
Article in European journal of nuclear medicine and molecular imaging, 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
backgroundNeuroimaging with [
objectivesTo determine whether GBA1 and APOE ε4 status are associated with diverging [
methodsWe analyzed [
resultsAPOE ε4 status mainly influenced the CIS, with APOE ε4-negative patients showing greater preservation of the DLB-typical CIS pattern (p = 0.03) compared to APOE ε4 carriers. In contrast, GBA1 status influenced global metabolic phenotype. GBA1 carriers showed a more homogeneous PD/DLB-like metabolic pattern in the machine learning model (p = 0.003) compared to GBA1 non-carriers, whereas the latter group demonstrated greater heterogeneity and higher expression of the AD-related metabolic pattern (p = 0.004). These effects were observed along a metabolic spectrum rather than as distinct clusters.
conclusionsAPOE ε4 and GBA1 modulate distinct aspects of the metabolic phenotype in DLB. GBA1 non-carriers and APOE ε4 carriers showed a higher rate of atypical metabolic signatures, which may contribute to biological heterogeneity and increase the risk of diagnostic misclassification.
