Development and validation of machine learning models for distant metastasis of primary hepatic carcinoma: a population-based study.

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
backgroundPrimary liver cancer is the sixth most common cancer globally and ranks third in cancer-related mortality. Patients with distant metastasis (PLCDM) have particularly low survival rates and are more difficult to treat. This study aims to identify risk factors associated with distant metastasis and overall survival (OS) in primary liver cancer and to determine the optimal predictive models using machine learning.
methodsWe extracted data from the SEER database (Incidence-SEER Research Data, 17 Registries, Nov 2022 Sub (2000-2020)) and identified risk factors for distant metastasis using logistic regression. Eight machine learning models were constructed using the "tidymodels" package in R and evaluated based on ROC curves, AUC, and accuracy. Cox regression was used to identify risk factors for OS, and Cox and Random Survival Forest (RSF) models were compared using time-dependent ROC curves. The best-performing model was interpreted using Shapley analysis. We also developed user-friendly web applications using the "shiny" package in R for clinical use.
resultsMultivariate analysis identified grade, T stage, N stage, tumor size, and surgery as independent risk factors for PLCDM. The Random Forest (RF) model showed the best performance with AUC values of 0.836, 0.817, and 0.846 in the training, internal validation, and external validation cohorts, respectively, and favorable Brier scores and accuracy. Shapley analysis ranked the risk factors by contribution as surgery, T stage, tumor size, N stage, and grade. Cox regression identified grade, surgery, and T stage as independent prognostic factors for OS. The Cox model outperformed the RSF model in time-dependent ROC analysis. Calibration and decision curve analysis (DCA) further confirmed its strong predictive performance and clinical utility. Shapley analysis ranked the risk factors as grade, surgery, and T stage.
conclusionsWe successfully constructed and validated optimal models for predicting PLCDM and its prognosis. These models provide valuable tools to guide clinical decision-making for PLCDM.
