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
Aim: The prognosis of hepatocellular carcinoma with extrahepatic spread (HCC-EHS) remains poor. While systemic therapy is standard, intrahepatic progression often drives mortality. This study evaluated whether combining transarterial chemoembolization (TACE) with sorafenib (TACES) improves outcomes versus TACE alone in HCC-EHS. Methods: In this multicenter, retrospective study, 423 HCC-EHS patients (Child-Pugh A) were categorized into TACE-alone (n = 294) or TACES (n = 129) groups. The primary endpoint was overall survival (OS). Inverse probability of treatment weighting (IPTW) was used to adjust for confounding. Radiological response was assessed per mRECIST. Results: After IPTW adjustment, the TACES group demonstrated significantly superior tumor response, with higher objective response (33.3% vs 16.4%, p = 0.004) and disease control rates (63.2% vs 46.3%, p = 0.008) compared to the TACE-alone group. This translated into a significant survival benefit, with a median OS of 10.4 months for TACES versus 7.0 months for TACE alone (IPTW-adjusted hazard ratio: 0.68; 95% CI: 0.52-0.88; p = 0.004). The survival advantage remained consistent in landmark analyses. Subgroup analyses indicated that the absolute benefit from combination therapy was most pronounced in patients with high intrahepatic tumor burden and preserved liver function. Conclusion: This real-world study demonstrates that in carefully selected patients with HCC-EHS, a combination of TACE and sorafenib provides significantly better tumor control and survival outcomes than TACE monotherapy. These findings suggest that an integrated therapeutic strategy, which aggressively manages the intrahepatic disease in conjunction with systemic therapy, can improve outcomes in this challenging-to-treat population and warrants validation in prospective studies.
