1 · What the graph read from it

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.

2 · The registry

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

Objectives: The goal is to design and validate a noninvasive screening model for advanced colorectal neoplasia(ACN) utilizing routine blood tumor markers and inflammatory indices, and to develop an online calculator for assessing individual risk. Methods: In this retrospective analysis, 1,290 patients who underwent colonoscopy and had full preoperative blood test results were included. Based on pathology, patients were categorized into a group with advanced colorectal neoplasms and another with non-advanced neoplasms. Patients were randomly assigned to a training set, making up 70%, and a test set, making up 30%.Candidate variables were initially screened using univariate logistic regression, and those with statistical significance were then included in a multivariate logistic regression model to determine independent predictors. To assess potential nonlinear relationships between continuous variables and the risk of advanced neoplasms, restricted cubic splines were employed. Prediction models were constructed using five machine learning algorithms and evaluated using the area under the receiver operating characteristic curve. The robustness of key predictors was further assessed through sensitivity and stratified analyses. SHAP was applied to interpret the final model, which was subsequently implemented as an online calculator. Results: Among the 1,290 patients, 210 were diagnosed with advanced colorectal neoplasms. CEA, SII, NLR, ALB, and PLR were identified as independent predictors, and their associations remained stable across sensitivity and stratified analyses. Among the models, XGBoost achieved the best performance, with an AUC of 0.956 (95% CI 0.936-0.976). SHAP analysis identified SII as the most influential predictor. Conclusion: A machine learning model based on key blood markers such as CEA, SII, and NLR can effectively support noninvasive screening for advanced colorectal neoplasms. This online calculator is a convenient and practical resource for evaluating risk on an individual basis in clinical practice.
