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

rationaleThe vesicular monoamine transporter 2 (VMAT2) has been identified as a potential target for the treatment of methamphetamine (METH) abuse. GZ-793A is a potent and selective VMAT2 inhibitor that has been shown to block the primary and conditioned reinforcing effects of METH, while demonstrating no abuse liability when given alone.

objectivesThe aim of the current study was to determine if GZ-793A attenuates METH- or cue-induced reinstatement of METH-seeking after a period of extinction. The effect of acute GZ-793A on locomotor activity also was assessed.

methodsAfter a period of extinction, rats were administered GZ-793A (15 mg/kg, s.c.) 15 min prior to a priming injection of METH or re-exposure to cues associated with METH infusions. GZ-793A also was administered 20 min prior to an injection of METH (0.5 mg/kg, s.c.) or saline to determine its effect on locomotor behavior.

resultsPretreatment with GZ-793A (15 mg/kg) decreased cue-induced reinstatement, without demonstrating any response suppressive effects when administered in the absence of reinstating stimuli. GZ-793A also decreased methamphetamine-induced reinstatement; however, response suppressant effects of GZ-793A were obtained when the compound was presented alone. In this latter experiment, GZ-793A may have reduced responding for the conditioned reinforcing effects of the contingently available cues rather than having nonspecific effects on baseline responding. GZ-793A had no effect on locomotor activity when administered alone or with METH.

conclusionsGZ-793A and related VMAT2 inhibitors may be promising leads for reducing the risk of relapse to METH use following exposure to drug-associated cues.
