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

Objectives: The combination of atezolizumab plus bevacizumab (A+B) represents one of the standards first-line treatments for unresectable hepatocellular carcinoma (HCC). Metformin has garnered attention for its potential antitumour and immunomodulatory properties beyond glycaemic control. This study aimed to assess metformin's impact in patients with type 2 diabetes mellitus (T2DM) receiving A+B therapy. Methods: This retrospective analysis of a prospectively-maintained multicentre database included 523 patients with HCC treated with A+B from the ARTE (Atezolizumab-bevacizumab Real-life Experience for Treatment of Hepatocellular Carcinoma) dataset across 18 Italian centres (May 2020-January 2024). We evaluated objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and time to progression (TTP) using Cox regression analysis and Inverse Probability of Treatment Weighting (IPTW) to address confounding. Results: Among 523 patients, 341 (65.2%) did not have diabetes and 182 (34.8%) had T2DM. In the overall population, metformin showed no significant benefit for PFS (HR = 1.15, 95% CI [0.88-1.50], Conclusion: This study found no evidence of improved outcomes with metformin use in patients with HCC in particular with T2DM receiving A+B therapy. Routine metformin use should not be expected to enhance A+B efficacy based on current evidence.
