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
introductionCerebrospinal fluid (CSF) biomarkers for Alzheimer's disease (AD) are essential for the early identification of non-amnestic phenotypes. Increased levels of total tau (t-tau) and phosphorylated tau (p-tau) have been reported in atypical AD cases, although the specific pattern remains a subject of debate. This study aimed to evaluate CSF biomarker profiles in relation to clinical phenotype. MATERIALS AND
methodsA retrospective review was performed, analyzing demographic data, time to diagnosis, clinical phenotype, and core AD biomarkers (beta-amyloid peptide 1-42 (Aβ1-42), t-tau, p-tau) in CSF from patients evaluated at University Hospital in Navarra between 2019 and 2022.
resultsThe study included 57 patients (54% female, mean age 67 years), of whom 41 met AD diagnostic criteria. Among these, 10 patients (25%) presented with atypical phenotypes (50% aphasic, 30% frontal, 20% mixed non-amnestic). Compared with the amnestic phenotype, the atypical group exhibited significantly higher t-tau (562.9 pg/mL vs 320.3 pg/mL, p = 0.021) and p-tau (81.5 pg/mL vs 37.7 pg/mL, p = 0.016) levels, independent of age, sex, and time to diagnosis.
conclusionsAtypical cases demonstrated increased tau levels, suggesting earlier and more extensive cortical damage than the amnestic phenotype. These findings underscore the significance of CSF biomarkers in phenotypic differentiation, disease course prediction, and individualized treatment strategies for AD.
