ICU-EEG Pattern Detection by a Convolutional Neural Network.
Article in Annals of clinical and translational neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivePatients in the intensive care unit (ICU) often require continuous EEG (cEEG) monitoring due to the high risk of seizures and rhythmic and periodic patterns (RPPs). However, interpreting cEEG in real time is resource-intensive and heavily relies on specialized expertise, which is not always available. This study introduces a lightweight convolutional neural network (CNN) to automatically detect key EEG patterns, including seizures and RPPs.
methodsWe classified time-frequency spectrograms of EEG data from the Harmful Brain Activity Classification challenge, including 1950 patients. We tested our model on a subset of this dataset and a small independent cohort of ICU patients with epileptic seizures from the Geneva University Hospital.
resultsOur model showed good performance metrics on the open-source data with an AUROC score of 93% for SZ, 91% for lateralized PD, 94% for generalized PD, 87% for lateralized RDA, 89% for generalized RDA, and 88% for others. The evaluation with the Geneva University Hospital dataset also demonstrated strong temporal detection capabilities, showing an false positive rate (FPR) of 22%, 20%, and 21% at 50 s, 30 s, and 20 s before seizure onset, and a true positive rate (TPR) of 76%, 84%, and 89% at 20 s, 30 s, and 50 s after seizure onset.
interpretationThis study presents a lightweight CNN model capable of detecting critical EEG patterns in ICU patients with minimal preprocessing. Moreover, the model's design provides reliable detection of ICU-EEG epileptic patterns shortly after their onset. These features underscore the model's potential to enhance timely EEG monitoring in resource-limited and advanced clinical contexts.
