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

Electrospun fibers show potential as a topical delivery system for vaginal microbicides. Previous reports have demonstrated delivery of anti-HIV and anti-STI (sexually transmitted infection) agents from fibers formulated using hydrophilic, hydrophobic, or pH-responsive polymers that result in rapid, prolonged, or stimuli-responsive release, respectively. However, coaxial electrospun fibers have yet to be evaluated as a highly tunable microbicide delivery vehicle. In this research, we explored the opportunities and limitations of a model coaxial electrospun fiber system to provide broad and tunable release rates for the HIV entry inhibitor maraviroc. Specifically, we prepared ethyl cellulose (EC)-shell and polyvinylpyrrolidone (PVP)-core fibers that were capable of releasing actives over a range of hours to several days. We further demonstrated simple and effective methods for combining core-shell fibers with rapid-release formulations to provide combined instantaneous and sustained maraviroc release. In addition, we investigated the effect of varying release media on maraviroc release from core-shell fibers, and found that release was strongly influenced by media surface tension and drug ionization. Finally, in vitro cell culture studies show that our fiber formulations were not cytotoxic and that electrospun maraviroc maintained similar antiviral activity compared to neat maraviroc.
