A Hepatitis B Virus-Derived Peptide Can Inhibit Infection of Human Lung Cells with SARS-CoV-2 in a Type-1 Interferon-Dependent Manner.
Article in Viruses, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The current COVID-19 pandemic has highlighted the urgent need to develop effective therapeutic strategies. We evaluated the in vitro antiviral effect against SARS-CoV-2 of a hepatitis B virus (HBV) hexamer peptide, Poly6, which is capable of eliciting an antiviral effect against human immunodeficiency virus -1 (HIV-1), as a novel HIV-1 integrase inhibitor, and a strong anticancer immune response in an IFN-I-dependent manner, as a novel potential adjuvant in anticancer immunotherapy. Here, we report that Poly6 exerts an anti-SARS-CoV-2 effect, with an estimated 50% inhibitory concentration of 2.617 µM, in the human bronchial epithelial cell line, Calu-3 but not in Vero-E6 cells, which are deficient in type 1 interferon (IFN-I) signaling. We proved via assays based on mRNA profiles, inhibitors, or blocking antibodies that Poly6 can exert an anti-SARS-CoV-2 effect in an IFN-I-dependent manner. We also found that Poly6 inhibits IL-6 production enhanced by SARS-CoV-2 in infected Calu-3 cells at both the transcription and the translation levels, mediated via IL-10 induction in an IFN-I-dependent manner. These results indicate the feasibility of Poly6 as an IFN-I-inducing COVID-19 drug with potent antiviral and anti-inflammatory activities.
