1 · What the graph read from 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.

2 · The registry

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

purposeLocoregional therapies (LRT) are employed for bridging patients with hepatocellular carcinoma (HCC) awaiting orthotopic liver transplantation (OLT). Although the main LRT options include transarterial chemoembolization (TACE) and radiofrequency ablation (RFA), percutaneous ethanol injection (PEI) is an alternative with considerably lower costs. This study is a pioneering evaluation of the natural history of PEI bridging to OLT as compared to TACE.

methodsAll consecutive cirrhotic patients with HCC enlisted for OLT (2011-2020) at a single center were analyzed. Patients were divided into three LRT modality groups: PEI, TACE, and PEI+TACE. The primary study outcome was waitlist dropout due to tumor progression beyond Milan criteria. A comparison of post-transplant outcomes of patients as stratified by LRT modality also was performed.

resultsOne hundred twenty-nine patients were included (PEI=56, TACE=43, PEI+TACE=30). The dropout rate due to tumor progression was not different among the three groups: PEI=8.9%, TACE=14%, PEI+TACE=16.7% (p=0.54). Thirteen (76.4%) patients underwent OLT after successful downstaging (3 [75%] in the PEI group, 5 [83.3%] in the TACE group, and 5 [71.4%] in the PEI+TACE group). For the 96 patients undergoing OLT, 5-year post-transplant recurrence-free survival was PEI=55.6% vs. TACE=55.1% vs. PEI+TACE=71.4% (p=0.42). Complete/near-complete pathological response rate was similar among groups (p=0.82).

conclusionDropout rates and post-transplant recurrence-free survivals related to PEI were comparable to those of TACE. This study supports the use of PEI alone or in combination with TACE for HCC patients awaiting OLT whenever RFA is not an option.
