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: Hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) face a very poor prognosis. And it remains unclear whether sequential surgery following conversion therapy based on immunotherapy combined with targeted therapy can yield long‑term survival benefits. This study aims to evaluate the long-term efficacy and safety of hepatocellular carcinoma patients with portal vein tumor thrombus receiving sequential surgery following conversion therapy with a combination of targeted therapy and immunotherapy, thereby demonstrating the therapeutic potential of this regimen. Methods: Data from 76 HCC patients with PVTT treated with programmed death-1 (PD-1) inhibitors and tyrosine kinase inhibitors (TKIs) followed by surgical treatment at Chinese People's Liberation Army General Hospital (June 2019 to June 2024) were analyzed. Recurrence-free survival (RFS) and overall survival (OS) were primary endpoints. Results: The median RFS was 21 months; the median OS was 62 months. RFS rates at 6 months, 1 year, 2 years, and 3 years were 76.2%, 59.7%, 48.1%, and 42.5%, respectively. OS rates at 6 months, 1 year, 2 years, 3 years, and 5 years were 98.7%, 93.4%, 78.1%, 72.4%, and 45.5%, respectively. Cox regression showed that preoperative alpha-fetoprotein (AFP) ≥20 ng/mL was an independent mortality factor, while non-major-pathological-response (non-mPR) and tumor size >50 mm were independent recurrence factors. Adverse events and surgical complications were evaluated, with no patient deaths resulting from conversion therapy or sequential radical surgery. Conclusions: For HCC patients with PVTT who achieve successful conversion and undergo radical surgery, sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors (ICIs) and anti-angiogenic targeted drugs (AATDs) is associated with favorable RFS and OS, and appears safe and effective. These findings suggest that this regimen may represent a promising option for these patients.
