1 · What the graph read from it

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.

2 · The registry

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

backgroundInfluenza A is a virus that affects a wide range of animals and also human beings. Avian influenza virus (AIV) subtype H9N2 has the potential to create influenza pandemic and vaccination is a common solution for this problem. The vaccine, used for rapid intervention, should be safe to use and highly effective, after a single administration. Chitosan nanoparticles (CNP) have already been recommended as a new adjuvant for inactivated AIV H9N2 vaccine immunization.

objectivesThis study aimed at the evaluation and better understanding of optimum concentration of CNP preparations and also, assessment of loading capacity of AIV into CNP, as an adjuvant in specific pathogen-free (SPF) chickens. MATERIALS AND

methodsFor measurement of vaccine-antibody response, different types of CNP were injected intramuscularly, in a single dose, to 21-day-old specific pathogen-free chickens. Chickens were monitored for the efficacy of the nanoparticles and, also, their immune response, during a follow up of 7 weeks, by using hemagglutination-inhibition (HI) test. The CNP were prepared according to modified ionic gelation method and inactivated antigen was loaded in four hemagglutinin units (HAU) concentrations. Loading capacity of nanoparticles was determined by hemagglutination (HA) method. Inactivated A/H9N2 AIV was mixed with chitosan of low molecular weight.

resultsThe CNP did not cause any mortality or side effects, when chickens were administered the prepared vaccine. The results strongly showed that this novel vaccine significantly enhances the immunogenicity of inactivated AIV, comparing with ISA70 (SEPPIC, Puteaux, France) adjuvant that is used routinely in the Razi Serum and Vaccine Research and Production Institute, Karaj, Iran, to reduce ISA70's side effects.

conclusionsThe AIV loaded into CNP vaccines induce appropriate antibody titers, after a single immunization, while requiring a low dose of antigen. The CNP also represent an interesting new platform for antigen delivery and a promising adjuvant candidate for H9N2 inactivated influenza vaccine.
