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

Filoviruses (Ebola and Marburg) cause severe hemorrhagic fever. There are five species of ebolavirus; among these, the Ebola (Zaire) and Sudan viruses (EBOV and SUDV, respectively) are highly pathogenic and have both caused recurring, large outbreaks. However, the EBOV and SUDV glycoprotein (GP) sequences are 45% divergent and thus antigenically distinct. Few antibodies with cross-neutralizing properties have been described to date. We used antibody engineering to develop novel bispecific antibodies (Bis-mAbs) that are cross-reactive toward base epitopes on GP from EBOV and SUDV. These Bis-mAbs exhibit potent neutralization against EBOV and SUDV GP pseudotyped viruses as well as authentic pathogens, and confer a high degree (in one case 100%) post-exposure protection of mice from both viruses. Our studies show that a single agent that targets the GP base epitopes is sufficient for protection in mice; such agents could be included in panfilovirus therapeutic antibody cocktails.
