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.
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
Rift Valley fever virus (RVFV) poses a continued threat to human health and animal husbandry. Two neutralizing and protective human monoclonal antibodies (mAbs), RVFV-268 and RVFV-379, exhibit similar affinities and epitope footprints on the Gn glycoprotein component of the RVFV Gn-Gc capsomeric lattice. Here, we define fine details of the biophysical determinants of Gn recognition used by RVFV human monoclonal antibodies through studying an antibody encoded by a set of recombined genes not previously identified in RVFV antibodies. We find that RVFV-379 exhibits a larger footprint than that observed for RVFV-268 and other antibodies targeting the same region, which involves major contributions of both the light and heavy chains. RVFV-379 also uses an oblique angle of approach towards the virion surface that contrasts with the perpendicular angle of engagement observed for some other potently neutralizing human mAbs. Further, consistent with amino acid sequence variation within and proximal to the RVFV-379 epitope, in vitro neutralization screening reveals a limited degree of neutralization breadth across prevalent RVFV strains, suggesting that RVFV has fewer functional constraints at this region of the virus envelope. By dissecting the molecular determinants of mAb recognition of Gn, this integrated analysis refines strategies needed for the rational design of vaccines that can elicit a potent and species-wide protective antibody immune response to this important re-emerging pathogen.
