Fusion color space analysis of tongue image characteristics in different stages of metastatic colorectal cancer and three-class model construction.
Article in Frontiers in physiology, 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
Objective: Color spaces were used to analyze the color characteristics of tongue image in different stages of metastatic colorectal cancer (mCRC), and a three-class model was constructed to predict the different tongue characteristics during the mCRC progression. Methods: Tongue images of CRC patients were collected and classified into non-metastatic, oligometastatic, and extensive metastatic groups according to tumor metastasis. The color components in HSB, Lab, and YCrCb color spaces were measured from tongue images and the differences in color characteristics were quantitatively analyzed. Based on the modified YOLO and combined with the expert model and multilayer perceptron (MLP) fusion framework, the three classification models of tongue images were constructed. Results: Most of the quantitative results showed the quantitative results for oligometastasis were the smallest values among the three metastatic stages. The Conclusions: In this study, tongue feature variations across different stages of CRC were successfully analyzed. A well-performing three-classification tongue image analysis model based on the YOLO architecture was initially constructed.
