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: Synchronous metastatic nasopharyngeal carcinoma (smNPC) demonstrates marked prognostic heterogeneity, which cannot be captured by conventional Cox proportional hazards (CoxPH) models owing to their limitations in managing complex, nonlinear relationships. We employed various machine learning (ML) techniques to enhance predicting overall survival (OS) in patients with smNPC. Methods: In this multicenter retrospective study, we conducted an analysis of 404 patients diagnosed with smNPC. We developed and assessed prognostic models utilizing a traditional Cox proportional hazards model alongside six ML algorithms. The predictive performances of these models were compared using the concordance index (C-index) and time-dependent area under the curve (tAUC). Risk stratification was conducted to guide personalized treatment strategies, and Kaplan-Meier survival curve analyses were performed to evaluate the efficacy of different treatment regimens across subgroups. Results: The random survival forest (RSF) model yielded the highest C-index of 0.746 and an average tAUC of 0.801 for OS, identifying RSF as the optimal predictor. Shapley additive explanations analysis revealed that five features were most influential: number of metastatic lesions, involved organs, first-line regimen, presence of liver metastasis, and using immunotherapy. Risk stratification, based on Kaplan-Meier survival curve analyses, demonstrated that local treatment of metastatic lesions significantly extended OS in low- and high-risk patient cohorts. Primary site radiotherapy conferred a survival advantage exclusively to low-risk patients, whereas immunotherapy yielded improved outcomes in high-risk patients (all p < 0.05). Conclusions: The RSF model excelled at predicting OS for patients with smNPC, providing reliable prognostic insights to guide risk-based treatment decisions in clinical practice.
