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
backgroundArtificial intelligence (AI) has increasingly been integrated into various fields of medicine, necessitating rigorous oversight by scientists to ensure its appropriate application. This study presents an analysis of microhemorrhages, which are closely associated with significant cerebrovascular events. Researchers have designed a study to investigate the feasibility of utilizing AI in the detection and assessment of microhemorrhages.
methodsThe study retrospectively analyzed 108 patients with cerebral microhemorrhagic foci and 108 controls using cranial magnetic resonance imaging (MRI) and susceptibility-weighted sequences, following ethical approval. Deep learning models, including a customized DenseNet for classification and nnU-Net for segmentation, were trained on preprocessed MRI data to detect and localize microhemorrhages efficiently.
resultsThe study involved a total of 216 patients with and without cerebral microbleeds. There were a total of 146 foci in the 108 patient group. The classification model demonstrated an area under the curve of 80% ± 2.7% and an accuracy of 75% ± 1.7%, though specificity was more limited at 68% ± 4.3%. The segmentation model identified microhemorrhagic regions with a sensitivity of 89.4% ± 1.4% and achieved a Dice similarity coefficient of 62.05% ± 2.3%.
conclusionOverall, both models demonstrated the potential for detecting and localizing microhemorrhages in 3D MRI data, though the classification model showed moderate specificity. The findings suggest that AI-based approaches may eventually serve as a supportive tool for microhemorrhage detection, provided further refinements are made to enhance detection accuracy and clinical applicability.
