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

Background: Outcomes after liver resection (LR) and liver transplantation (LT) for hepatocellular carcinoma (HCC) are heterogenous and may vary by region, over time periods and disease burden. We aimed to compare overall survival (OS) and disease-free survival (DFS) between LT versus LR for HCC within the Milan criteria. Methods: Two authors independently searched Medline and Embase databases for studies comparing survival after LT and LR for patients with HCC meeting the Milan criteria. Meta-analyses and metaregression were conducted using random-effects models. Results: We screened 2,278 studies and included 35 studies with 18,421 patients. LR was associated with poorer OS [hazard ratio (HR) =1.44; 95% confidence interval (CI): 1.14-1.81; P<0.01] and DFS (HR =2.71; 95% CI: 2.23-3.28; P<0.01) compared to LT, with similar findings among intention-to-treat (ITT) studies. In uninodular disease, OS in LR was comparable to LT (P=0.13) but DFS remained poorer (HR =2.95; 95% CI: 2.30-3.79; P<0.01). By region, LR had poorer OS versus LT in North America and Europe (P≤0.01), but not Asia (P=0.25). LR had inferior survival versus LT in studies completed before 2010 (P=0.01), but not after 2010 (P=0.12). Cohorts that underwent enhanced surveillance had comparable OS after LT and LR (P=0.33), but cohorts undergoing usual surveillance had worse OS after LR (HR =1.95; 95% CI: 1.24-3.07; P<0.01). Conclusions: Mortality after LR for HCC is nearly 50% higher compared to LT. Survival between LR and LT were similar in uninodular disease. The risk of recurrence after LR is threefold that of LT.
