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

Recent epidemics of West Nile virus (WNV) around the world have been associated with significant rates of mortality and morbidity in humans. To develop standard WNV diagnostic tools that can differentiate WNV from Japanese encephalitis virus (JEV), four monoclonal antibodies (MAbs) specific to WNV envelope (E) protein were produced and characterized by isotyping, reactivity with denatured and native antigens, affinity assay, immunofluorescence assay (IFA), and epitope competition, as well as cross-reactivity with JEV. Two of the MAbs (6A11 and 4B3) showed stronger reactivity with E protein than the others (2F5 and 6H7) in Western blot analysis. 4B3 could bind with denatured antigen, as well as native antigens in indirect ELISA, flow cytometry analysis, and IFA; whereas 2F5 showed highest affinity with native antigen. 4B3 and 2F5 were therefore used to establish an antigen capture-ELISA (AC-ELISA) detection system. The sensitivity of this AC-ELISA was 3.95 TCID(50)/0.1 ml for WNV-infected cell culture supernatant. Notably, these MAbs showed no cross-reactivity with JEV, which suggests that they are useful for further development of highly sensitive, easy handling, and less time-consuming detection kits/tools in WNV surveillance in areas where JEV is epidemic.
