A cell-penetrating bispecific antibody suppresses hepatitis B virus replication and secretion.
Article in Virus research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Hepatitis B virus (HBV) represents one of the major pathogenic factor that leads to chronic liver diseases and the development of hepatocellular carcinoma (HCC). The currently approved anti-HBV drugs cannot eradicate the virus or block the development of HCC. HBV nucleocapsid consists of the hepatitis B core antigen (HBcAg) and the HBV relaxed-circular partially double-stranded DNA (rcDNA), indispensable in virus replication. The present study reported a cell-penetrating bispecific antibody targeting HBcAg and preS1, fused with the cell-penetrating peptide R9TAT, named Anti-preS1 × Anti-HBcAg-R9TAT. The antibody could recognize preS1 and HBcAg and internalize into living cells efficiently, suppressing the extracellular hepatitis B surface antigen (HBsAg) and hepatitis B envelope antigen, and the intracellular HBsAg and HBcAg in vitro. This cell-penetrating bispecific antibody is a novel approach to suppressing HBV replication and secretion and is a promising anti-HBV therapeutic antibody candidate.
