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
The membrane permeability of nucleotide-based drugs, such as sofosbuvir (Sovaldi), requires installation of phosphate-caging groups. One strategy, termed "ProTide", masks the anionic phosphate through an N-linked amino ester and an O-linked aromatic phospho-ester, such that release of the active drug requires consecutive enzymatic liberation by an esterase and then a phosphoramidase, such as Hint1. Because Hint1 is known to be selective for nucleotides, it was not clear if the ProTide approach could be deployed for non-nucleotides. Here, we demonstrate that caging of a phosphate-containing inhibitor of the prolyl isomerase Pin1 increases its permeability. Moreover, this compound was processed by both esterase and phosphoramidase activity, releasing the active molecule to bind and inhibit Pin1 in cells. Thus, Hint1 appears to recognize a broader set of substrates than previously appreciated. It seems possible that other potent, but impermeable, phosphate-containing inhibitors might likewise benefit from this approach.
