Efficacy and safety of PD-1/PD-L1 inhibitors combined with tyrosine kinase inhibitors as first-line treatment for hepatocellular carcinoma: a meta-analysis and trial sequential analysis of randomized controlled trials.

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 use of immune checkpoint inhibitors (ICIs) in treating hepatocellular carcinoma (HCC) has grown significantly. However, the therapeutic benefits of ICIs alone are notably modest. This meta-analysis assesses the efficacy and safety of using PD-1/PD-L1 inhibitors in conjunction with tyrosine kinase inhibitors (TKIs) for patients with advanced or unresectable HCC. Methods: An extensive search of the literature was performed using databases such as PubMed, Web of Science, Embase, and the Cochrane Library, capturing randomized controlled trials (RCTs) until 16 October 2024. Efficacy was measured by progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and disease control rate (DCR). Safety was gauged through the occurrence of treatment-related adverse events (TRAEs). Hazard ratios (HRs) for PFS and OS, along with risk ratios (RRs) for ORR, DCR, and TRAEs, were calculated, each with 95% confidence intervals (CIs). Heterogeneity among studies was quantified using Cochran's Q test, I Results: This analysis incorporated 4 studies with a total of 2,174 patients. Treatment regimens combining PD-1/PD-L1 inhibitors with TKIs significantly improved PFS (HR = 0.694, 95% CI: 0.527-0.914; 95% PI: 0.228-2.114) and ORR (RR = 2.303, 95% CI: 1.360-3.902; 95% PI: 0.408-12.991) compared with first-line monotherapy or TKI monotherapy in the overall population. Subgroup analysis indicated that the improvements in PFS and OS were particularly significant among patients of Asian descent or those with hepatitis B virus (HBV) infection (all Conclusion: This study revealed that combining PD-1/PD-L1 inhibitors with TKIs in the treatment of advanced or unresectable HCC leads to superior clinical outcomes compared to first-line monotherapy or TKIs alone, particularly in patients with HBV infection and those of Asian descent. Clinicians are advised to be vigilant regarding the potential for TRAEs in clinical settings.
