Noninvasive prediction model for predicting spontaneous tumor necrosis in hepatocellular carcinoma and prognostic study.
Article in European journal of gastroenterology & hepatology, 2025. 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
BACKGROUND AND
objectivesIn hepatocellular carcinoma (HCC), patients with spontaneous tumor necrosis have a high recurrence rate and poor prognosis. However, conventional preoperative imaging could not detect the presence of tumor necrosis. Accordingly, we developed and assessed a nomogram to forecast tumor necrosis.
methodsClinical data were collected retrospectively from 495 patients with HCC who received a hepatectomy at Zhongnan Hospital of Wuhan University from 1 January 2015 to 31 May 2024. The patients ( n = 495) were randomly divided in a 7 : 3 ratio into the training cohort (TC, n = 348) and the validation cohort (VC, n = 147). The logistic regression analyses were used to identify factors independently predicting tumor necrosis in the patients with TC. The Kaplan-Meier survival analysis was used for comparing and estimating survival rates.
resultsPreoperative clinical tumor-node-metastasis stage, hemoglobin, systemic immune inflammation, alkaline phosphatase, and alpha-fetoprotein levels were identified as hazard factors for predicting tumor necrosis. The area under the receiver operating characteristic curve of the TC, VC, and the full cohort was 0.810, 0.758, and 0.795, respectively. The calibration curves demonstrated a high degree of concordance. The decision curve analysis showed the clinical significance of the nomogram. Both overall survival and recurrence-free survival of patients in the tumor necrosis group were poorer.
conclusionOur predictive model could effectively predict the risk of spontaneous tumor necrosis in patients with HCC, and tumor necrosis was related to a worse prognosis.
