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
purposesSleep apnea or hypopnea is a sleep-related breathing disorder characterized by insufficient ventilation during sleep. Sleep apnea is classified into two major forms: obstructive sleep apnea (OSA) and central sleep apnea (CSA). The conventional diagnosis with Polysomnography (PSG) is time-consuming, uncomfortable, and costly in the clinical setting. To address these issues, wearable devices and AI techniques have been developed, utilizing single or multi-modal physiological signals. This study aims to deploy a multi-modal approach by analyzing both EEG and ECG signals derived from home sleep testing devices for OSA/CSA/hypopnea identification. A robust ensemble learning model is proposed to compare with the performance of the deep learning model in event classification.
methodsEEG and ECG signals from 201 PSG were collected. Non-linear features extracted by wavelet transform methods and machine learning were used to develop a classification algorithm. ECG spectrograms and the deep learning model were also deployed to compare with traditional method. Two classification strategies including 3-class (OSA-hypopnea-normal, OSA-CSA-normal) and 2-class (OSA-hypopnea, OSA-CSA) were also examined.
resultsThe highest classification performance was achieved using the combined signal-based model with 98.8% accuracy, 99.1% sensitivity, and 98.5% specificity for classifying OSA and CSA. When compared with the deep learning model, the classification accuracy of the combined signal-based machine learning model was significantly higher in almost all classification strategies.
conclusionThe findings highlight the effectiveness of combining non-linear features from ECG and EEG signals for classifying various sleep-related breathing events. A proposed machine learning model provides significantly precise classification compared to a deep learning approach, offering improved reliability in-home sleep setting.
