Association between cerebral microbleeds and cognition in a memory clinic population.

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
backgroundThe cognitive consequences of cerebral microbleeds (CMBs) in memory clinic population with a diverse cognitive spectrum remain unclear.
objectivesThis study aimed to investigate how CMBs at different locations are associated with cognitive performance in a memory clinic population and whether these associations are independent of related small vessel disease (SVD) markers.
designA cross-sectional study.
settingA university hospital memory clinic. Data were collected from December 2004 to September 2014 and analyzed in June 2024.
participantsA total of 910 participants, composed of 64 individuals with subjective cognitive decline, 399 with mild cognitive impairment (MCI), 339 with Alzheimer disease dementia (AD), 58 with vascular dementia and mixed dementia, and 50 with other types of dementia, were included. MAIN OUTCOMES AND MEASURES: Summary scores for global cognition, memory, language, visuospatial function, and executive function measured by the Consortium to Establish a Registry for Alzheimer's disease (CERAD) neuropsychological battery.
resultsIn the overall population, the presence of deep/infratentorial CMBs was significantly associated with executive dysfunction; however, this association was attenuated after adjusting for related SVD markers. When stratified by diagnostic subgroup, strictly lobar CMBs were significantly associated with impairments in global cognition and memory in the MCI group, independent of related SVD markers. In contrast, no significant associations between CMBs and cognitive domains were observed in the AD group.
conclusionsThese findings, based on memory clinic population with a broad cognitive spectrum, suggest that CMBs, depending on their location, may have different implications for cognitive function.
