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 interactions between the N- and C-terminal heptad repeat (NHR and CHR) regions of the human immunodeficiency virus (HIV-1) glycoprotein gp41 create a structure comprising a 6-helix bundle (SHB). A sequence in the SHB named the "pocket" is crucial for the SHB's stability and for the fusion inhibitory activity of 36-residue NHR peptide N36. We report that a short 27-residue peptide, N27, which lacks the pocket sequence, exhibits potent inhibitory activity in both cell-cell and virus-cell fusion assays when fatty acids were conjugated to its N but not C terminus. Furthermore, mutations in the positions that prevent interaction with the CHR but not with the NHR resulted in a dramatic reduction in N27 activity. These data support a mechanism in which N27 mainly targets the CHR rather than the internal NHR coiled-coil, reveal the N-terminal edge of the endogenous core structure in situ and hence complement our recent findings of the C-terminal edge of the core, and provide a new approach for designing short inhibitors from the NHR region of other lentiviruses due to similarities in their envelope proteins.
