Peg-IFNα reduces clinical severity but cannot prevent COVID-19 infection in chronic hepatitis B patients: a cohort study in China.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
Introduction: SARS-CoV-2/HBV coinfections are increasingly common as SARS-CoV-2 continues to evolve. The interferon (IFN) therapy for HBV infection might also have antiviral effects against SARS-CoV-2. To understand the effects of IFN on SARS-CoV-2 infection, we compared the clinical characteristics between IFN-treated chronic hepatitis B (CHB) patients and nucleo(s)tide analogs (NAs)-treated CHB patients during their SARS-CoV-2 infection. Methods: Our cohort study enrolled patients with primary SARS-CoV-2 infections among IFN-treated and NAs-treated CHB patients during the Omicron wave in Shanghai, China, from December 7 2022 to January 23 2023. Clinical characteristics and self-reported acute symptoms during SARS-CoV-2 infection were collected by telephone questionnaire in January 2023. Results: The four most common symptoms were fever, fatigue, cough and sore throat among all enrolled participants, regardless of their treatment. Interestingly, Pegylated interferon-alpha (Peg-IFNα) treated CHB patients had a significantly higher proportion of asymptomatic infection than NAs-treated CHB patients (14.53% vs. 2.70%, Conclusion: In this real-world cohort of CHB patients infected with SARS-CoV-2 during the Omicron wave, Peg-IFNα treatment was associated with milder self-reported acute clinical manifestations, including a higher proportion of asymptomatic infection and reduced occurrence of several common symptoms.
