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

rationaleThe mesolimbic dopamine (DA) system is considered a principal site for nicotine-cocaine interactions. OBJECTIVES AND

methodsThe aim of this paper is to study the effects of local perfusions (through the microdialysis cannula) of nicotinic acetylcholine receptor (nAChR) antagonists in the ventral tegmental area (VTA, where mesolimbic DA cell bodies are located) or nucleus accumbens (nAc, where mesolimbic DA nerve terminals project) on cocaine-elicited increase in DA levels in the nAc of mice using intracerebral microdialysis.

resultsIntra-nAc perfusion of mecamylamine (a nonselective central nicotinic antagonist) or coperfusion of methyllycaconitine (MLA, 10 nM) and dihydro-beta-erythroidine (DHbetaE, 10-100 muM) decreased cocaine-elicited increase in DA perfusate levels. In contrast, intra-nAc perfusion of MLA alone (a relatively selective antagonist of alpha7 subunit-containing nAChRs) increased, while DHbetaE (a relatively selective antagonist of heteromeric nAChR subtypes) did not alter, cocaine-elicited increase in DA perfusate levels. Intra-VTA perfusion of MLA (100 nM) or DHbetaE (100 micro M) significantly increased the cocaine-elicited increase of DA levels in the nAc or VTA, whereas DHbetaE and MLA coperfusion or mecamylamine perfusion had no significant effect.

conclusionsThese results show that intra-nAc and intra-VTA perfusion of nAChR antagonists differentially affect cocaine-elicited increase in DA levels in a region and subtype-specific manner. This suggests that multiple cholinergic/nicotinic pathways influence the effects of cocaine on mesolimbic DA neurons in complex, and sometimes opposing, patterns.
