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

3-Methoxy-2-(methylamino)-1-(4-methylphenyl)propan-1-one (mexedrone) appeared in 2015 and was advertised by UK Internet retailers as a non-controlled mephedrone derivative (2-(methylamino)-1-(4-methylphenyl)propan-1-one), which was of particular interest to countries who operate generic drugs legislation. This study describes the synthesis and analytical characterization of mexedrone and the differentiation from its isomer, N-methoxymephedrone, which was predicted to be a suitable candidate before the identity of mexedrone was revealed. A full analytical characterization is described using various chromatographic, spectroscopic and mass spectrometric platforms and X-ray crystal structure analysis. The analytical data obtained for a vendor sample were consistent with the synthesized mexedrone reference standard and analytical differentiation between the mexedrone and N-methoxymephedrone positional isomers was achieved. Furthermore, α-chloromethylmephedrone was identified as a by-product during mexedrone synthesis. All three substances were also studied for their uptake and releasing properties at dopamine transporters (DAT), norepinephrine transporters (NET) and serotonin transporters (SERT) using in vitro monoamine transporter assays in rat brain synaptosomes and compared to mephedrone. Mexedrone was a weak non-selective uptake blocker with IC
