Rapid repetitive syllable sounds associate with episodic memory, executive function, and working memory in cognitively healthy and subjectively impaired older adults.

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
Non-invasive screening tools for Alzheimer's disease (AD) risk are needed. Decline in episodic memory and subjective cognitive impairment (SCI) are both associated with elevated AD risk. We investigated associations between three cognitive domains (episodic memory, executive function, and working memory) and motor speech performance in older adults with healthy cognition (HC) or SCI. In total, 1014 community-dwelling participants (cross-sectional sample: 843 HC, mean 66.9 years, 72.8% female; 171 SCI, mean 66.3 years, 70.8% female) remotely completed cognitive tests (Paired Associates Learning and Spatial Working Memory from the Cambridge Neuropsychological Test Automated Battery) and motor speech tests (Tasmanian [TAS] Test). We evaluated whether acoustic motor speech features extracted from 10-s tests of "pa," "ta," or "ka" syllable repetition improved episodic memory, executive function, and working memory regression models over age, sex, education, anxiety, and depression (ΔAIC > 2). Motor speech features improved estimation of cognitive scores over fixed demographic and clinical variables in each group and cognitive domain. In summary, we found associations between motor speech performance and cognition in older adults. Short motor speech tests demonstrate potential for non-invasive, cost-effective AD risk screening. Longitudinal research is needed to investigate relationships between individual motor speech features and cognitive changes confirmed to result from the progression of AD.
