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

rationaleStudies indicate that adolescence is a time of increased sensitivity to the rewarding effects of nicotine, and that stress is associated with an increased risk for smoking initiation in this age group. It is possible that stress leads to increased nicotine use in adolescence by augmenting its rewarding properties. Corticotropin-releasing factor type 1 receptors (CRF-R1) mediate physiological and behavioral stress responses. They may also mediate stress-induced potentiation of activity in multiple neural substrates implicated in nicotine reward.

objectivesThe aim of the present study was to determine the effect of acute stressor exposure on single trial nicotine conditioned place preference (CPP) in adolescent male rats using a biased CPP procedure and the role of CRF-R1 in this effect.

resultsA single episode of intermittent footshock administered 24 h before the start of place conditioning dose-dependently facilitated acquisition of CPP to nicotine (0.2, 0.4, and 0.6 mg/kg). Pretreatment with CP-154,526 (20 mg/kg), a selective CRF-R1 antagonist, 30 min before footshock exposure significantly attenuated the effect of prior stress to facilitate nicotine CPP acquisition. CP-154,526 pretreatment had no effect in animals conditioned with a nicotine dose that produced CPP under non-stress conditions, suggesting a specific role for CRF-R1 following stress.

conclusionsTaken together, the results suggest that during adolescence, nicotine reward is enhanced by recent stressor exposure in a manner that involves signaling at CRF-R1. Information from studies such as this may be used to inform efforts to prevent and treat adolescent nicotine dependence.
