The aperiodic and periodic activities of EEG dynamically relate with cognitive performance in schizophrenia.

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
Background: Aperiodic and periodic activities of electrophysiological signals have strong correlation with various neurocognitive factors. In the current study, we aim to investigate the aperiodic exponent and periodic oscillations (alpha and beta band power) and their associations with cognitive performance in schizophrenia (SCZ). Methods: We enrolled 32 SCZ patients and 33 healthy controls (HC) for the study. Cognitive performance was assessed using the total Brief Assessment of Cognition in Schizophrenia (BACS). Before and after the language comprehension tasks (humor, metaphor and irony), the 5-min eyes-closed and eyes-open EEG signals were collected respectively. The aperiodic exponent and periodic power were extracted and obtained according to the division of brain regions. Finally, Pearson correlation was used to examine the relationships between the EEG parameters and behavioral measures. Results: SCZ participants exhibited higher aperiodic exponents and lower periodic oscillations compared to HC. The aperiodic exponent decreased significantly after the tasks in central location ( Conclusions: Our findings confirmed the higher aperiodic exponent with lower alpha and beta band in SCZ, along with the variability and task-responsiveness of the aperiodic exponent. The findings suggest that aperiodic exponent holds strong cognitive functional implications in SCZ.
