Evaluation of multivalent H2 influenza pandemic vaccines in mice.
Article in Vaccine, 2017. 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
Subtype H2 Influenza A viruses were the cause of a severe pandemic in the winter of 1957. However, this subtype no longer circulates in humans and is no longer included in seasonal vaccines. As a result, individuals under 50years of age are immunologically naïve. H2 viruses persist in aquatic birds, which were a contributing source for the 1957 pandemic, and have also been isolated from swine. Reintroduction of the H2 via zoonotic transmission has been identified as a pandemic risk, so pre-pandemic planning should include preparation and testing of vaccine candidates against this subtype. We evaluated the immunogenicity of two inactivated, whole virus influenza vaccines (IVV) in mice: a monovalent IVV containing human pandemic virus A/Singapore/1/1957 (H2N2), and a multivalent IVV containing human A/Singapore/1/1957, avian A/Duck/HongKong/319/1978 (H2N2), and swine A/Swine/Missouri/2124514/2006 (H2N3) viruses. While both vaccines induced protective immunity compared to naïve animals, the multivalent formulation was advantageous over the monovalent in terms of level and breadth of serological responses, neutralization of infectious virus, and reduction of clinical disease and respiratory tissue replication in mice. Therefore, multivalent pandemic H2 vaccines containing diverse viruses from animal reservoirs, are a potential option to improve the immune responses in a pre-pandemic scenario where antigenic identity cannot be predicted.
