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

MMP-9 plays a detrimental role in the pathology of several neurological diseases and, thus, represents an important target for intervention. The water-soluble prodrug ND-478 is hydrolyzed to the active MMP-9 inhibitor ND-322, which in turn is N-acetylated to the even more potent metabolite ND-364. We used a sensitive bioanalytical method based on ultraperformance liquid chromatography with multiple-reaction monitoring detection to measure levels of ND-478, ND-322, and ND-364 in plasma and brain after administration of ND-478 and the metabolites. ND-478 did not cross the blood-brain barrier, as was expected; however the active metabolites ND-322 and ND-364 distributed to the brain. The active compound after administration of either ND-478 or ND-322 is likely ND-364. ND-322 is N-acetylated in both brain and liver, but it is so metabolized preferentially in liver. Since N-acetyltransferases involved in the metabolism of ND-322 to ND-364 are polymorphic, direct administration of the N-acetylated ND-364 would achieve the requisite therapeutic levels in the brain.
