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

Abuse of amphetamine analogues, such as methamphetamine (METH), represents an important health problem because of their powerful addictive and neurotoxic effects. Abuse of METH induces dopamine neuron terminals loss and cell death in the striatum similar to what is found in other neurodegenerative processes. Exposing mice and rats to enriched environments (EE) has been shown to produce significant protective effects against drug-induced reward as well as against neurodegenerative processes. Here, we investigated whether exposure to EE could reduce the METH-induced reward and neurotoxicity. For this, we reared mice for 2 months during early stages of life in standard environments or EE and then, at adulthood, we tested the ability of METH to induce conditioned place preference and neurotoxicity. We found that, contrary to what we found with other drugs such as cocaine and heroin, EE was unable to reduce the rewarding effects of METH. In addition, contrary to what we found with other toxins such as MPTP, EE did not diminish the striatal neurotoxicity induced by METH (4 x 10 mg/kg) as measured by dopamine content, tyrosine hydroxylase protein levels and apoptosis. Our results demonstrate that the rewarding and neurotoxic effects of METH are not reduced by EE and highlight the great risks associated with the increased popularity of this drug amongst the young population.
