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

The highly pathogenic avian influenza (HPAI) H5N8 virus has been detected in wild birds and poultry worldwide. The threat caused by HPAI H5N8 virus still exists with concerns for human infection. The preparedness for epidemic prevention and decreasing the agricultural and economic lost is extremely important. Hemagglutinin (HA), a surface glycoprotein of influenza viruses, is considered as the major target for detection of the influenza virus subtype in the infected samples. In this study, the recombinant H5N8 HA1 and HA2 proteins were expressed in Escherichia coli, and were utilized to generate two monoclonal antibodies, named 7H6C and YC8. 7H6C can bind the HA proteins of H5N1 and H5N8, but cannot bind the HA proteins of H1N1, H3N2, and H7N9, indicating that it has H5-subtype specificity. In contrast, YC8 can bind the HA proteins of H1N1, H5N1, and H5N8, but cannot bind the HA proteins of H3N2 and H7N9, indicating that it has H1-subtype and H5-subtype specificity. The epitope sequences recognized by 7H6C are located in the head domain of H5N8 HA, and are highly conserved in H5 subtypes. The epitope sequences recognized by YC8 are located in the stalk domain of H5N8 HA, and are highly conserved among the H1 and H5 subtypes. 7H6C and YC8 can be applied for specific detection of the HA proteins of H5N8 and H5Nx avian influenza viruses. KEY POINTS: • The mAb 7H6C or YC8 was generated by using the HA1 or HA2 of the HPAI H5N8 virus as the immunogen. • 7H6C recognized the head domain of H5N8 HA, and YC8 recognized the stalk domain of H5N8 HA. • 7H6C and YC8 can detect the HA proteins of H5Nx subtypes specifically.
