Nomogram for Predicting Severe Abdominal Pain During Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma: A Retrospective Study.
Article in Journal of pain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: To develop and validate a nomogram for identification of hepatocellular carcinoma (HCC) patients unsuitable for percutaneous radiofrequency ablation (RFA) due to severe abdominal pain. Methods: In this retrospective study, 530 patients with HBV-HCC underwent RFA between February, 2014, and April, 2024, and treated in the affiliated hospital of Changhai Hospital, Naval Medical University. Patients were divided into a modeling group (373 cases) and a validation group (157 cases) at a 7:3 ratio. Pain severity during the heating process of the radiofrequency ablation system was assessed using the Visual Analog Scale (VAS). Logistic regression was used to determine risk factors for severe pain, based on which a nomogram was developed. Results: Key predictors of severe abdominal pain included tumor distance to capsule <1cm, tumor distance to portal vein <1cm, and history of transarterial chemoembolization (TACE) ( Conclusion: Tumor distance to capsule, tumor distance to portal vein, and TACE history are independent factors influencing severe abdominal pain during radiofrequency ablation in HBV-HCC patients. The nomogram effectively identifies HCC patients at risk of severe pain during RFA, facilitating doctors to decide on better alternative locoregional therapies.
