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

Vaccination is the most effective method of preventing the spread of the influenza virus. However, the traditional intramuscular (IM) immunization causes fear, pain, and cross infection. In contrast, needle-free (NF) immunization is quick and easy for medical personnel and painless and safe for patients. In this study, we assessed the safety and protective efficacy of NF intradermal (ID) immunization with the influenza H7N9 split vaccine (Anhui H7N9/PR8). A preliminary safety evaluation showed that ID immunization with 15 μg of the H7N9 influenza vaccine was not toxic in rats. Moreover, the antigen was metabolized more rapidly after ID than after IM immunization, as determined by in vivo imaging, and ID immunization accelerated the generation of a specific immune response. Additionally, ID immunization with a 20% dose of the H7N9 split vaccine Anhui H7N9/PR8 offered complete protection against lethal challenge by the live H7N9 virus. Taken together, our findings suggest that NF ID immunization with the H7N9 influenza vaccine induces effective protection, has a good safety profile, requires little antigen, and elicits an immune response more rapidly than does IM immunization. This approach may be used to improve the control of influenza H7N9 outbreaks.
