Safety and Efficacy of Radiofrequency Ablation for Solitary Hepatocellular Carcinoma (3-5 cm): a Propensity Score Matching Cohort Study.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundWe aim to investigate the safety and efficacy of radiofrequency ablation in the treatment of solitary hepatocellular carcinoma (3-5 cm) in comparison with surgical resection.
methodsIncluded in this study were 388 patients with primary and solitary hepatocellular carcinoma, of whom 196 patients underwent surgical resection and the other 192 patients received radiofrequency ablation. Clinicopathological characteristics, prognosis, post-treatment complications, hospital stay, and financial expenditures between the two groups were compared retrospectively.
resultsThe result of propensity score matching and subgroup analysis showed that the 1-, 3-, and 5-year overall survival and disease-free survival were comparable in patients with tumors of 3-4 cm in diameter between surgical resection and radiofrequency ablation groups. However, when the tumor size exceeded 4 cm in diameter, surgical resection exhibited a superior long-term prognosis compared with radiofrequency ablation. Nevertheless, hepatectomy was associated with high occurrences of postoperative complications, long hospital stay, and high hospitalization cost as compared with radiofrequency ablation. Further analysis of the relationship between tumor size and pathological features of hepatocellular carcinoma showed that tumors larger than 4 cm were positively correlated with a high rate of microvascular invasion and satellite nodule formation.
conclusionFor solitary hepatocellular carcinoma of 3-4 cm in diameter, radiofrequency ablation could achieve a comparable prognosis with a low incidence of post-treatment complications and low hospitalization costs, while surgical resection is recommended for solitary hepatocellular carcinoma tumors of 4-5 cm in diameter when long-term prognosis is considered.
