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

purposePregabalin is a novel GABA-analogue approved for the treatment of partial onset seizures, neuropathic pain, and general anxiety disorder. Pregabalin has been classified as a Schedule V drug with a low risk of inflicting abuse or addiction. However, some publications have indicated that pregabalin may have a potential for abuse among patients with past or current opiate addiction. Thus, we hypothesized that pregabalin might be abused by patients who were undergoing an opiate replacement therapy and never had an indication for taking pregabalin on medical grounds.

methodsUrine specimens from 124 patients with opiate dependency syndrome and from 111 patients with other addiction disorders (alcohol, benzodiazepines, cannabis, amphetamines) were screened for pregabalin by means of a mass spectrometer analysis.

resultsWe found 12.1 % of all urine specimens from patients with opiate addiction to be positive for pregabalin. None of the patients concerned had a medical indication for using pregabalin. In the control group, 2.7 % of the patients were tested positively for pregabalin, due to their taking it regularly for chronic pain or general anxiety.

conclusionsOur data suggest that pregabalin is liable to be abused among individuals with opiate dependency syndrome Thus, vigilance and caution are called for when patients with a past or current opiate dependency are exposed to treatment with pregabalin.
