Curative treatment is feasible for recurrent hepatocellular carcinoma regardless of recurrence pattern after hepatitis C virus eradication with interferon-free direct-acting antiviral therapy.

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
backgroundInterferon (IFN)-free direct-acting antivirals (DAAs) have significantly improved hepatitis C virus (HCV) elimination rates. However, new-onset or recurrence of hepatocellular carcinoma (HCC) remains common even after achieving sustained virological response (SVR). This study investigated the clinical significance and treatability of HCC recurrence patterns after SVR, which have not been fully explored yet.
methodsWe retrospectively analyzed the risk factors for HCC development in 279 patients with HCV-associated chronic liver disease who achieved SVR with DAA therapy after July 2014. Twenty-eight patients with HCC recurrence after SVR were classified by the type of recurrence (intrahepatic metastasis, hypervascularization, and de novo). Correlation between tumor markers (alpha-fetoprotein and des-γ-carboxy prothrombin) at the time of previous HCC and at the time of recurrence was examined.
resultsThirty-three patients (11.8%) developed HCC after SVR. Multivariate analysis revealed that a history of HCC was the only independent risk factor for HCC development after SVR (hazard ratio 14.4, P < 0.001). Among the 28 patients with HCC recurrence, intrahepatic metastasis was observed in eight (29%), hypervascularization in seven (25%), and de novo recurrence in six (21%) patients. At the time of recurrence, 27 patients (96%) had Barcelona clinic liver cancer stage 0/A disease. Curative treatment was possible in 27 patients (96%).
conclusionsHCC recurrence after SVR was detected early, regardless of the recurrence pattern, allowing for the selection of curative treatment. In the DAA era, HCC recurrence after SVR in patients with a history of HCC could be appropriately managed through strict follow-up.
