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
Speech production relies on precise integrations between vocal and auditory feedback mechanisms for fluent verbal communication. This study investigated how explicit attentional instructions influence speech auditory feedback control. A total of forty-three participants performed speech vowel vocalizations while receiving brief (200 ms) and randomized pitch shifts at ±100 cents magnitude in their auditory feedback during concurrent electroencephalography (EEG) recordings. Twenty-one participants were randomly assigned to an attentional-instruction group and were instructed to focus their attention on detecting pitch-shift stimuli via pressing a button whereas no such instructions were provided for the remaining twenty-two participants in the no-instruction group. Behavioral data revealed a significantly smaller peak magnitude of vocal compensation responses to auditory feedback alterations in the attentional-instruction compared with no-instruction group, suggesting an attentional modulation of the speech motor control mechanisms. Time-frequency analyses of EEG data showed a significantly stronger desynchronization of the high-beta band (20-30 Hz) neural activities for the attentional-instruction group, indicating enhanced audio-vocal integration when participants attentively monitored their speech feedback. In addition, we found that the accuracy of button-press responses for detecting pitch shifts positively correlated with the alpha and beta band power (8-30 Hz) while compensation magnitude positively correlated only with the gamma band power (30-80 Hz). These findings provide new insights into the effects of attentional instruction on the neural and behavioral correlates of speech motor control, emphasizing its application as a viable tool for targeted treatment of speech disorders in clinical populations.
