Perivascular versus nonperivascular hepatocellular carcinoma treated with liver resection: a retrospective propensity score matching comparison of long-term outcomes.

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.
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: The outcomes for perivascular hepatocellular carcinoma (HCC) and nonperivascular HCC after hepatectomy have not been well illustrated. This study aimed to compare long-term outcomes between perivascular and nonperivascular HCC. Methods: A total of 714 HCC patients were retrospectively collected and categorized into perivascular and nonperivascular groups according to whether the tumors had contact with branches of the portal or hepatic vein. A 1:1 propensity score matching (PSM) with a caliper of 0.02 was used to eliminate bias. Disease-free survival (DFS) and overall survival (OS) were assessed using the Kaplan-Meier method, and long-term survival analyses were conducted. Results: After PSM, 249 pairs of patients were enrolled in a nonadjacent portal vein (nPV) group and an adjacent portal vein (aPV) group. Additionally, 268 pairs of patients were enrolled in a nonadjacent hepatic vein (nHV) group and an adjacent hepatic vein (aHV) group. The aPV group had significantly worse DFS than the nPV group (5-year recurrence rates: 69.3% Conclusions: HCC adjacent to the portal vein negatively impacted the prognosis, whereas the hepatic vein did not appear to have such an influence.
