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

rationaleMethylone, a new drug of abuse sold as "bath salts," has similar effects to ecstasy or cocaine.

objectiveWe have investigated changes in dopaminergic and serotoninergic markers, indicative of neuronal damage induced by methylone in the frontal cortex, hippocampus, and striatum of mice, according to two different treatment schedules.

methodsMethylone was given subcutaneously to male Swiss CD1 mice at an ambient temperature of 26 °C. Treatment A consisted of three doses of 25 mg/kg at 3.5-h intervals between doses for two consecutive days, and treatment B consisted of four doses of 25 mg/kg at 3-h intervals in 1 day.

resultsRepeated methylone administration induced hyperthermia and a significant loss in body weight. Following treatment A, methylone induced transient dopaminergic (frontal cortex) and serotoninergic (hippocampus) impairment. Following treatment B, transient dopaminergic (frontal cortex) and serotonergic (frontal cortex and hippocampus) changes 7 days after treatment were found. We found evidence of astrogliosis in the CA1 and the dentate gyrus of the hippocampus following treatment B. The animals also showed an increase in immobility time in the forced swim test, pointing to a depressive-like behavior. In cultured cortical neurons, methylone (for 24 and 48 h) did not induce a remarkable cytotoxic effect.

conclusionsThe neural effects of methylone differ depending upon the treatment schedule. Neurochemical changes elicited by methylone are apparent when administered at an elevated ambient temperature, four times per day at 3-h intervals, which is in accordance with its short half-life.
