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/aims: No standardized adjuvant treatment has been established for patients with hepatocellular carcinoma (HCC) following curative resection. This study aimed to evaluate the efficacy and safety of adjuvant tyrosine kinase inhibitors (TKIs) in combination with anti-programmed death-1 (PD-1) antibody in HCC patients with high-risk factors for recurrence. Methods: HCC patients who underwent hepatectomy at the First Affiliated Hospital, Sun Yat-sen University between January 2020 and December 2022 were retrospectively enrolled. Baseline differences were balanced between HCC patients with adjuvant therapy group (TKIs+PD-1, AT group) and hepatectomy alone group (HA group) by propensity-score matching (PSM). Recurrence-free survival (RFS) and overall survival (OS) were compared between these two groups. Univariable and multivariable analyses were used to identify prognostic factors, and a subgroup analysis was also conducted to assess treatment efficacy across different patient subpopulations. Results: A total of 357 HCC patients with high risk of recurrence was enrolled. After PSM, 50 matched pairs of patients were analyzed. After PSM, the median follow-up was 30.2 months (IQR 18.47-37.48). The median RFS was 25.77 months (95% CI: 15.07- not evaluated (NE)) in the AT group versus 7.7 months (95% CI: 5.43-15.2) in the HA group. The AT group demonstrated significantly longer RFS compared with the HA group ( Conclusions: Adjuvant TKIs combined with anti-PD-1 antibody significantly prolongs recurrence-free survival in HCC patients with high risk of postoperative recurrence. However, this combination does not confer a survival benefit in terms of overall survival. These findings support the potential clinical utility of adjuvant targeted immunotherapy in this high-risk population and highlight the need for further validation in prospective, randomized studies.
