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.

Abstract

backgroundLorcaserin is a modestly selective agonist for 2C serotonin receptors (5-HT METHODS AND

participantsWe evaluated effects of single 10 mg doses of lorcaserin on the subjective and reinforcing effects of cocaine, using a randomized, double-blind, within-subject, cross-over design. Male, non-treatment-seeking, regular cocaine users received either single doses of oral placebo (n = 9) or lorcaserin (n = 9), followed by low- or high- doses of intravenous cocaine (0.23 or 0.46 mg/kg-injection). They were then allowed to self-administer the lower dose of cocaine.

resultsCocaine was well tolerated after lorcaserin pretreatment. Oral lorcaserin did not modify the number of cocaine injections self-administered. However, it prolonged the time over which participants made intravenous choices relative to the duration of monetary (cash) decisions. Lorcaserin increased ratings of 'high' and 'stimulated' after low-dose cocaine or vehicle, but decreased craving for cocaine after intravenous vehicle. It also caused small but significant increases in heart rate following noncontingent injections of intravenous placebo or cocaine. When active cocaine was self-administered, lorcaserin decreased heart rate after selection of a monetary choice, but increased it following an intravenous choice.

conclusionsCombined treatment with cocaine and lorcaserin was safe in a limited number of subjects, but did not diminish cocaine-motivated behavior or drug-induced 'high'. Some positive subjective effects of cocaine were enhanced by lorcaserin, and it delayed intravenous choices and decreased craving under some conditions. Effects on heart rate depended on the type of reinforcer being self-administered.
