Machine Learning-Based Model for Predicting Recurrence-Free Survival After Interventional Therapy in Malnourished Hepatocellular Carcinoma Patients.

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
objectiveThis study intends to utilize machine learning approaches to screen out the crucial factors affecting the recurrence of hepatocellular carcinoma (HCC) patients with preoperative malnutrition after interventional therapy, and based on the identified factors, develop a nomogram for predicting the patients' 1-, 3-, and 5-year recurrence-free survival (RFS).
methodsThis study encompassed the clinical data of 512 malnourished (CONUT score ≥ 2) HCC patients who received the combination treatment of transarterial chemoembolization (TACE) and radiofrequency ablation (RFA) at Beijing You'an Hospital between January 2014 and January 2020. These patients were then randomly partitioned into training and validation cohorts at a 7:3 ratio. To investigate the factors influencing the post-treatment recurrence of malnourished HCC patients, methods such as random survival forest (RSF), eXtreme gradient boosting (XGBoost), and multivariate Cox regression analysis were employed. A nomogram was constructed based on the identified crucial factors to predict RFS in HCC patients. Subsequently, its performance was evaluated through Kaplan-Meier (KM) curves, receiver operating characteristic curve (ROC), calibration curve, and decision curve analysis (DCA).
resultsThis study determined that GGT, APTT, age, and ALT are independent risk factors influencing recurrence in malnourished HCC patients. Based on the four risk factors, a nomogram for predicting RFS was effectively developed. The KM curve analysis showed that the nomogram could significantly distinguish between patient groups with varying recurrence risks. Furthermore, the nomogram's discriminative ability, accuracy, and decision-making efficacy were validated through the above-mentioned evaluation indicators, collectively suggesting its robust predictive performance.
conclusionsWe developed a nomogram that can predict the 1-, 3-, and 5-year RFS of malnourished HCC patients after undergoing the combination treatment; the constructed nomogram exhibited favorable predictive capabilities.
