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

backgroundA small proportion of all hepatocellular carcinomas (HCCs) arise in a non-cirrhotic liver (NCL). However, our knowledge about the HCCs developing in a NCL is scarce. This study was undertaken to investigate the characteristics and survival course of this patient group.

methodsWe retrospectively analyzed the database of patients with HCC at a tertiary center during a 10-year period (2009-2019). All demographic, clinical, laboratory, and tumoral features with survival outcomes were compared between the HCC-CL and HCC-NCL groups.

resultsOut of 384 HCC cases, 11.2% (n = 43) had no cirrhosis. The dominant etiology in the HCC-NCL group was hepatitis B virus (n = 26, 60.5%), followed by non-alcoholic fatty liver disease (n = 10, 23.2%), and hepatitis C virus (n = 7, 16.3%). The maximum tumor diameter was approximately 2 times larger in the HCC-NCL group (HCC-NCL: 90 mm vs. HCC-CL: 46.5 mm, P < .001). The proportion of patients with vascular (HCC-NCL: 27.9% vs. HCC-CL: 8.6%, P < .001) and extrahepatic invasion (HCC-NCL: 14% vs. HCC-CL: 3%, P = .001) were prominently higher in the HCC-NCL group. Patients with HCC-NCL were less often detected in early-curable stages (BCLC 0-A) than those in the HCC-CL group (HCC-NCL: 16.3% vs. HCC-CL: 34.9%, P = .004). The overall survival was not different between the 2 groups (HCC-NCL: 19.4 ± 9.8 months vs. HCC-CL: 17.5 ± 2.3 months, P = .581).

conclusionHCC in NCL is diagnosed at more advanced tumoral stages with larger tumor size and more often with vascular and extrahepatic spread. Despite the preserved liver functions, the overall survival is not prolonged in HCCs without cirrhosis, due to the late recognition.
