Assessment of the Immunogenicity and Safety of an Inactivated Associated Vaccine Against Influenza and Newcastle Disease.
Article in Vaccines, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
BACKGROUND/
objectivesCombined vaccination against avian influenza (A/H5N3, A/H7N7) and Newcastle disease is of practical interest for reducing handling during immunization and for achieving timely protection in poultry. The aim of this study was to evaluate an inactivated combined (associated) vaccine containing antigenic variants of avian influenza viruses A/H5N3 and A/H7N7 and Newcastle disease virus (NDV). The vaccine is protected by Patent No. 87417.
methodsViruses with initial reproductive titers of 10
resultsFollowing vaccination, protective immunity was observed starting from day 14. HI titers peaked by day 30 (7.6-7.8 log
conclusionsThe developed inactivated combined vaccine induced HI antibodies and protective immunity against avian influenza (A/H5N3, A/H7N7) and Newcastle disease. The formulation concept supports flexible antigen combinations and enables group administration via drinking water, which may reduce handling compared with separate vaccinations.
