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 (PRG) is approved for the treatment of neuropathic pain, partial seizures and generalised anxiety disorder in many countries and currently under study for other indications. Supported by case reports and the results of a limited number of studies there is an ongoing debate on the potential of PRG to cause addictive behaviours. However, currently available evidence on this issue is sparse, and any definitive assessment of PRG's potential for abuse and dependence is not yet in sight. The aim of our study was to identify the number of cases of PRG abuse or dependence reported to the database of a German medical regulatory body and to obtain insights into further usage-specific parameters.

methodsWe conducted a query of the entire database of the German Federal Institute for Drugs and Medical Devices (BfArM) regarding reports of PRG abuse or dependence and analysed these cases on the basis of several parameters.

resultsA total of 55 reports of PRG abuse or dependence were identified (mean age 36 years, 64 % of reports involved males). The first reports were submitted to BfArM in 2008, and the reporting frequency has increased up to the present. Mean daily PRG dosage was 1424 mg. Current or previous polytoxicomania was present in 40 and 42 % of cases, respectively. Psychiatric diagnoses other than substance-related disorders were reported in 13 (24 %) cases. In about one-third of the patients withdrawal syndromes subsequent to discontinuation of PRG were reported.

conclusionsCases of PRG abuse or dependence have been reported to the BfArM since 2008, with a marked increase of such reports in subsequent years. Male sex and a history of polytoxicomania may be possible risk factors for the development of addictive behaviours related to PRG.
