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

Avian Influenza (AI) caused by the H9N2 subtype of the avian influenza virus (AIV) poses a serious threat to both the poultry industry and to public health safety. NP is one of the major structural proteins in influenza viruses. B-cell determinants located on NP proteins have attracted increasing attention. In this study, based on the NP sequence of the H9N2 (A/chicken/Shandong/LY1/2017) strain, the truncated NP gene (71 AA-243 AA) was cloned and prokaryotically expressed in a pET-28a (+) vector. BALB/c mice were immunized with a purified recombinant of an NP protein to prepare a monoclonal antibody against NP proteins. The prokaryotic expression of four overlapping fragments, NP-N-96, NP-C-103, NP-C-54 and NP-C-49, were used to recognize an antigenic epitope of the NP protein. The results show that, after cell fusion, one hybridoma cell clone secreted the antibody specific to the NP protein, following screening with ELISA and indirect immunofluorescence, which is named the 4F5 monoclonal antibody (mAb). Western blotting on the overlapping fragments showed that the
