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

backgroundAdministration of cocaine during adolescence alters neurotransmission and behavioral sensitization in adulthood, but the effect on the acquisition of fear memories and the development of emotion-based neuronal circuits is unknown.

methodsWe examined fear learning and anxiety-related behaviors in adult male rats that were subjected to binge cocaine treatment during adolescence. We furthermore conducted gene expression analyses of the amygdala 22 hours after the last cocaine injection to identify molecular patterns that might lead to altered emotional processing.

resultsRats injected with cocaine during adolescence displayed less anxiety in adulthood than their vehicle-injected counterparts. In addition, cocaine-exposed animals were deficient in their ability to develop contextual fear responses. Cocaine administration caused transient gene expression changes in the Wnt signaling pathway, of axon guidance molecules, and of synaptic proteins, suggesting that cocaine perturbs dendritic structures and synapses in the amygdala. Phosphorylation of glycogen synthase kinase 3 beta, a kinase in the Wnt signaling pathway, was altered immediately following the binge cocaine paradigm and returned to normal levels 22 hours after the last cocaine injection.

conclusionsCocaine exposure during adolescence leads to molecular changes in the amygdala and decreases fear learning and anxiety in adulthood.
