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

We previously described fusion-inhibitory peptides that are targeted to the cell membrane by cholesterol conjugation and potently inhibit enveloped viruses that fuse at the cell surface, including HIV, parainfluenza, and henipaviruses. However, for viruses that fuse inside of intracellular compartments, fusion-inhibitory peptides have exhibited very low antiviral activity. We propose that for these viruses, too, membrane targeting via cholesterol conjugation may yield potent compounds. Here we compare the activity of fusion-inhibitory peptides derived from the influenza hemagglutinin (HA) and show that although the unconjugated peptides are inactive, the cholesterol-conjugated compounds are effective inhibitors of infectivity and membrane fusion. We hypothesize that the cholesterol moiety, by localizing the peptides to the target cell membrane, allows the peptides to follow the virus to the intracellular site of fusion. The cholesterol-conjugated peptides trap HA in a transient intermediate state after fusion is triggered but before completion of the refolding steps that drive the merging of the viral and cellular membranes. These results provide proof of concept for an antiviral strategy that is applicable to intracellularly fusing viruses, including known and emerging viral pathogens.
