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

Accumulating evidence from human and rodent studies suggests that females are more sensitive to the motivating and rewarding properties of drugs of abuse. Numerous reports implicate estradiol in enhancing drug-related responses in females, yet the neurobiological mechanisms underlying this effect of estradiol are unknown. Because dendritic spine plasticity in the nucleus accumbens (NAc) is linked to the addictive effects of drugs, we examined the influence of estradiol on dendritic spines in this region. Previously our laboratory demonstrated that in female medium spiny neurons, estradiol activates metabotropic glutamate receptor subtype five (mGluR5), a G protein-coupled receptor already implicated in the etiology of drug addiction. Thus, we sought to determine whether mGluR5 is a part of the mechanism by which estradiol affects dendritic spine density in the NAc. To test this hypothesis, ovariectomized female rats were treated with the mGluR5 antagonist, MPEP, or vehicle prior to estradiol (or oil) treatment and 24 h later dendritic spine density was evaluated by DiI labeling and confocal microscopy. We found that estradiol decreased dendritic spine density in the NAc core and that pretreatment with MPEP blocked this effect. In contrast, MPEP had no effect on dendritic spine density in the NAc shell or CA1 region of the hippocampus, two regions in which estradiol increased the density of dendritic spines. As dendritic spine plasticity in the NAc core has behavioral consequences for drug addiction, these data provide a clue as to how estradiol acts in females to enhance behavioral responses to drugs of abuse.
