A Novel Chimeric Fiber-C4/D11 Subunit Vaccine Induces Cross-Neutralizing Antibodies and Provides Better Protection Against Fowl Adenovirus (FAdV) Type 4 and Type 11 Than the Fiber-D11/C4 Subunit Vaccine.

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 widespread prevalence of different serotypes of fowl adenoviruses (FAdVs) has led to diverse vaccine demands, especially for subunit vaccines targeting FAdV-4 and FAdV-11, which cause hydropericardium-hepatitis syndrome (HHS) and inclusion body hepatitis (IBH), respectively. Although the Fiber protein is known to elicit robust immune protection, further exploration is needed to enhance the production of cross-neutralizing antibodies. This study utilized structural prediction and homology modeling techniques, employing domain-swapping strategy to integrate neutralizing epitope-containing amino acid sequences (274-451aa and 364-543aa) into the shaft domain of the Fiber protein. Two novel chimeric proteins were recombinantly expressed and developed into subunit vaccines: Fiber-C4/D11 and Fiber-D11/C4. Immunogenicity assessments revealed that the Fiber-C4/D11 vaccine group rapidly induced an antibody response against FAdV-11 within 7 days post-vaccination. By 28 days post-vaccination (dpv), the Fiber-C4/D11 vaccine group exhibited significantly higher levels of cross-neutralizing antibodies compared to the Fiber-D11/C4 group (
