Characteristics of brain computed tomography in dementia with cardiovascular disease and psychological and behavioral symptoms.

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
Objective: To describe brain computed tomography (CT) features in Alzheimer's disease (AD) with comorbid cardiovascular diseases (CVDs) and examine associations with behavioral and psychological symptoms (BPSD). Methods: This single-center, hospital-based observational case-control study (August 2019-May 2021) used consecutive sampling. We enrolled 165 older adults with AD and CVDs (CVD group), 165 older adults with AD without CVDs (AD-only group), and 165 cognitively healthy older adults (healthy controls). All participants underwent non-contrast brain CT at baseline. Qualitative CT findings [cortical atrophy, widened sulci, and medial hippocampal cerebrospinal fluid (CSF) pool widening] and quantitative parameters (lateral split brain width, frontal sulcus width, lateral ventricle width, third ventricle width, forehead index, and caudate nucleus index) were compared across groups. Diagnostic performance for AD (AD groups vs. healthy controls) was evaluated using receiver operating characteristic (ROC) curves and the area under the curve (AUC). BPSD were assessed with the Neuropsychiatric Inventory Questionnaire (NPI-Q), and correlations between NPI-Q scores and CT parameters were analyzed in the CVD group. Results: Qualitative CT abnormalities were more frequent in both AD groups than in healthy controls ( Conclusion: AD participants, with or without CVD comorbidity, showed significant CT abnormalities compared with healthy controls. In AD with CVDs, quantitative CT parameters were associated with BPSD severity.
