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

World-wide methamphetamine (meth) use is increasing at a rapid rate; therefore, it has become increasingly important to understand the synaptic changes and neural mechanisms affected by drug exposure. In rodents, 6-h access to contingent meth results in an escalation of drug intake and impaired cognitive sequelae typically associated with changes within the corticostriatal circuitry. There is a dearth of knowledge regarding the underlying physiological changes within this circuit following meth self-administration. We assessed pre- and postsynaptic changes in glutamate transmission in the medial prefrontal cortex (mPFC) and nucleus accumbens (NAc) following daily 6-h meth self-administration. In the mPFC, meth caused postsynaptic adaptations in ionotropic glutamate receptor distribution and function, expressed as a decrease in AMPA/NMDA ratio. This change was driven by an increase in NMDA receptor currents and an increase in GluN2B surface expression. In the NAc, meth decreased the paired-pulse ratio and increased the frequency of spontaneous excitatory postsynaptic currents with no indication of postsynaptic changes. These changes in mPFC synapses and NAc activity begin to characterize the impact of meth on the corticostriatal circuitry.
