In-ovo Newcastle disease virus vaccine strain TS09-C protects commercial chickens against Newcastle disease in the presence of maternally derived antibodies.

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
Maternally derived antibodies (MDA) substantially interfere with active immunity in post-hatch vaccination, although they provide early protection against disease through passive immunity in young chickens. Previously, Newcastle disease virus (NDV) strain TS09-C was demonstrated to be safe and immunogenic as in-ovo vaccine in specific-pathogen-free chickens. Here, we evaluated the safety, protective efficacy, and duration of clinical protection of the TS09-C virus as an in-ovo vaccine for commercial chickens in the presence of Maternally derived antibodies against NDV. This vaccine was safe in commercial chickens and provided at least 80% protection against a virulent NDV challenge for 3 mo, despite inducing a low hemagglutinin-inhibition titer. For commercial chickens, the protective efficacy of the in-ovo vaccination was markedly higher than that of posthatch vaccination, and the cellular immune response might play an important role in the higher protective efficacy of the in-ovo vaccine. The overall results indicate that the maternally derived antibodies against NDV do not significantly interfere with the ability of the in-ovo vaccine strain TS09-C to induce protective cellular immunity.
