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
backgroundCurrently, reliable preoperative methods for predicting vertebral artery (VA) invasion are lacking. The authors develop a novel model based on MRI radiomic signatures combined with clinical and imaging features for predicting intraoperative vertebral artery injury in patients with primary cervical tumors.
methodsIncluded in this retrospective study were 168 patients who received surgical resection for primary cervical tumors. They were randomly assigned to a training set (n = 117) and a test set (n = 51) . Least absolute shrinkage and selection operator logistic regression was applied for feature selection and radiomic signature construction. A multilayer perceptron (MLP) model and 10 machine learning models were used to develop diverse prediction models. Independent risk factors of clinical variables were screened by Logistic regression, based on which a clinical model was constructed. A combined model was established by combining the radiomic signatures and clinical factors. The predictive performance of the combined model was evaluated in both training and test sets using Hosmer-Lemeshow test and decision curve analysis (DCA).
resultsAccording to the scoring system, the MLP model obtained the highest total score of 87, meaning that its prediction performance was the best of all evaluated models, so the MLP was selected to construct the radiomics model. The AUC of the combined model in the training and test cohorts was 0.951 and 0.950 respectively, and both were higher than that of the radiomics model (AUC 0.900 in training set, p = 0.010, AUC 0.780 in test set, p = 0.001) and the clinical model (AUC 0.740 in training set, p < 0.001, AUC 0.781 in test set, p = 0.008) alone.
conclusionThe present study presents a nomogram that incorporates radiomic signatures and clinical features, which could be used to predict the risk of intraoperative VA injury in patients with primary cervical tumors.
