Add-on PD-1 inhibitor with Peg-IFNα therapy favors functional cure of chronic hepatitis B patients.
Article in Journal of translational internal medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 and Objectives: The treatment options for hepatitis B surface antigen (HBsAg) clearance are limited for patients who have failed pegylated interferon-α (Peg-IFNα) therapy. Given preclinical evidence that PD-1 blockade boosts antiviral immunity, this study aims to evaluate the efficacy and safety of PD-1 inhibitors in chronic hepatitis B (CHB) patients who have failed interferon therapy. Methods: This non-randomized controlled trial was conducted in CHB patients who failed to achieve HBsAg clearance after 48 weeks of Peg-IFNα therapy. Including two groups: (i) a PD-1 inhibitor plus Peg-IFNα group receiving sintilimab 1 mg/kg/12 weeks plus Peg-IFNα 180 μg/week ( Results: The PD-1 inhibitor plus Peg-IFNα group included 33 patients and the Peg-IFNα group included 31 patients. At week 24, HBsAg clearance occurred in 30.3% of PD-1 inhibitor plus Peg-IFNα group Conclusions: Quarterly sintilimab add-on therapy triples the short-term HBsAg clearance rate in interferon-refractory CHB without major additional toxicity. A week-12 ALT surge and elevated OAS1 may serve as early biomarkers of response, but confirmation in larger randomized trials is needed.
