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

introductionThe present study aimed to evaluate the effect of poor differentiation and tumor size on survival outcome after hepatic resection of hepatocellular carcinoma (HCC).

methodsA total of 1,107 patients who underwent initial and curative hepatic resection for HCC without macroscopic vascular invasion participated in the study. Using the multivariable Cox proportional hazards regression model, we evaluated changes in hazard ratios (HRs) for the association between tumor differentiation and survival based on tumor size.

resultsIn patients with poorly (Por) differentiated HCCs, the adjusted HRs of reduced overall survival (OS), recurrence-free survival (RFS), early RFS, and early extrahepatic RFS were 1.31 (95% confidence interval [CI]; 1.07-1.59), 1.07 (95% CI 0.89-1.28), 1.31 (95% CI 1.06-1.62), and 1.81 (95% CI 1.03-3.17), respectively. Moreover, based on an analysis of the effect modification of tumor differentiation according to tumor size, Por HCC was found to be associated with a reduced OS (

conclusionsPor HCC measuring ≥2 cm was associated with early recurrence. Hence, it had negative effects on OS. After surgery, patients with Por HCC measuring ≥5 cm should be cautiously monitored for early extrahepatic recurrence. These findings will help physicians devise treatment strategies for patients with HCC.
