Y-Polyp: research on devices for detecting colorectal polyps with limited samples.
Article in BMC medical imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundsColonoscopy plays a crucial role in preventing the malignant transformation of colorectal polyps, with early diagnosis and detection of colorectal cancer being effective approaches to reducing incidence and mortality rates among patients. With the rise of neural networks, research on computer-aided detection of colorectal polyps has garnered increasing attention. However, existing computer-aided diagnostic systems are constrained by insufficient training sample sizes, making it difficult to train high-performance systems.
methodsThis paper proposes the Y-Polyp model for colorectal polyp detection. By employing a parallel strategy with multidimensional attention mechanisms, this model enables convolutional kernels to learn more flexible attention across four spatial dimensions, thus fully capturing target features from limited data samples. Additionally, the model filters conflicting information in spatial domains, suppressing inconsistent features and addressing inconsistencies among features at different scales. To validate the effectiveness of the Y-Polyp model, extensive experiments are conducted and evaluated using a Kvasir-SEG dataset.
resultsThe experimental results show that the Y-Polyp model significantly improves the accuracy in the detection of colorectal polyps. Specifically, the overall precision of the polyp detection model has increased by 3%, while the recall rate and average precision have increased by 2.7%, 2% and 2.7%, respectively.
conclusionsThis method exhibits strong generalization ability and robustness, adapting to various colonic structures and changes in target appearance, and the proposed colorectal polyp detection approach thus possesses wide applicability and reliability.
