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 relatively weak reinforcing effects of nicotine in experimental studies have been attributed to possible aversive effects or the need to space nicotine administrations over time to expose reinforcing effects.

objectiveThis study was designed to determine if the response-maintaining effects of nicotine are increased when availability is spaced through time, and whether nicotine is an effective punisher of remifentanil-maintained responding.

methodsCompared to a cocaine reference dose, nicotine dose and timeout (TO) value were varied in eight rhesus monkeys responding for intravenous (i.v.) nicotine on varying fixed-ratio (FR) schedules of reinforcement.The aversive effects of nicotine were evaluated in four animals choosing between a standard dose of remifentanil alone or in combination with one of several doses of nicotine.

resultsIn three of eight self-administration monkeys, 0.01 mg/kg/inj nicotine did not maintain responding at any FR value. In the other five animals, nicotine-maintained response rates increased with either FR or TO values to a certain point, and then slowed. Maximum nicotine-maintained response rates were much slower than those maintained by cocaine, and demand for nicotine was less than demand for cocaine. Nicotine was an effective punisher of remifentanil-maintained responding at doses ranging from 0.01 to 0.3 mg/kg/inj. Lower punishing dose seemed to be related to the absence of reinforcing effects within subject.

conclusionThere are an order of magnitude individual differences in sensitivity to both the reinforcing and punishing effects of nicotine, and this drug may be unique in being a weak positive reinforcer in small doses and aversive in large doses.
