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

backgroundIn the United States, nearly 30% of liver transplants (LT) are performed for hepatocellular carcinoma (HCC). Although overall long-term survival is highest with LT, there are limited data on the incremental survival benefit of LT versus other curative options (resection or ablation) due to shunting of patients towards LT.

methodsWe performed a retrospective cohort study of patients aged 50-69 with cirrhosis and HCC in the Veterans Health Administration (population enriched with 3 curative treatments) from 2008 to 2016. The cohort was restricted to patients who received LT, resection, or ablation and a calculated model for end-stage liver disease score <15 at HCC diagnosis.

resultsAmong 2129 veterans in the analytic cohort, 658 (26.7%) received LT, 244 (11.5%) underwent resection, and 1317 (61.59%) received ablation. In multivariable models, patients who underwent resection (hazard ratio: 5.42; 95% confidence interval: 4.15-7.08) or ablation (hazard ratio: 5.50; 95% confidence interval: 4.51-6.71) had significantly increased hazards of death. However, in absolute terms, the incremental survival benefit of LT over resection or ablation was small, between 0.02 and 0.03 years at 1 year, 0.32-0.42 years at 3 years, and 1.04-1.24 years at 5 years follow-up. These results were consistent in sensitivity analyses accounting for possible immortal time bias, as well as a cohort restricted to early/intermediate stage HCC.

conclusionsAlthough LT is associated with significantly increased survival compared to resection and ablation, the absolute incremental survival benefit is small over a 5-year time horizon. Optimal selection of patients for LT is critical for maximizing utilization of a scarce resource.
