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

rationaleCorticotropin-releasing factor (CRF) and noradrenaline (NA) have been shown in independent studies to mediate stress-induced reinstatement of drug seeking. To date, however, a functional interaction between the systems in reinstatement has not been demonstrated.

objectivesThe objectives of this study were to determine whether CRF and NA systems can interact to influence reinstatement responding and, if so, in what direction the interaction occurs. MATERIALS AND

methodsRats were trained to self-administer cocaine (0.23 mg/kg per infusion) for 8-10 days. Subsequently, responding for drug was extinguished, and tests for reinstatement were conducted following: (1) pretreatment with the CRF receptor antagonist, D: -Phe CRF(12-41) [1 microg, intracerebroventricular (i.c.v.)], prior to i.c.v. injections of NA (10 microg; Experiment 1); (2) pretreatment with the alpha(2) adrenoceptor agonist, clonidine (40 microg/kg, i.p.), prior to i.c.v. injections of CRF (0.5 microg; Experiment 2); (3) pretreatment with D: -Phe (1, 5 microg, i.c.v.), prior to systemic injections of the alpha(2) adrenoceptor antagonist, yohimbine (1.25 mg/kg; Experiment 3A); or (4) pretreatment with clonidine (40 microg/kg, i.p.) prior to systemic injections of yohimbine (0.625 mg/kg, 1.25 mg/kg; Experiment 3B).

resultsNA reliably induced reinstatement, an effect that was blocked by pretreatment with D: -Phe. In contrast, CRF-induced reinstatement was not attenuated by pretreatment with clonidine. Pretreatment with neither D: -Phe nor clonidine was effective in blocking yohimbine-induced reinstatement.

conclusionTogether, the present findings suggest a functional interaction between NA and CRF systems in mediating stress-induced reinstatement of cocaine seeking, whereby activation of CRF receptors occurs subsequent to, and downstream of, the sites of action of NA.
