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

Attempts to prevent HIV infection through pre-exposure prophylaxis (PrEP) include topical application of anti-HIV drugs to the mucosal sites of infection; however, a potential role for local drug metabolizing enzymes in modulating the exposure of the mucosal tissues to these drugs has yet to be explored. Here we present the first report that enzymes belonging to the cytochrome P450 (CYP) and UDP-glucuronosyltransferase (UGT) families of drug metabolizing enzymes are expressed and active in vaginal and colorectal tissue using biopsies collected from healthy volunteers. In doing so, we discovered that dapivirine and maraviroc, a non-nucleoside reverse transcriptase inhibitor and an entry inhibitor currently in development as microbicides for HIV PrEP, are differentially metabolized in colorectal tissue and vaginal tissue. Taken together, these data should help to guide the optimization of small molecules being developed for HIV PrEP.
