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

backgroundDespite their favourable toxicology profile, benzodiazepines and the related Z-drugs (zopiclone, zolpidem and zaleplon) have been associated with physiological tolerance, dependence and addiction. Evidence of harm (e.g., falls, motor vehicle collisions and cognitive disturbances) has been reported in older populations. The aim of this study was to determine the relation between users' characteristics and the use of benzodiazepines and Z-drugs in Manitoba over a 16-year period.

methodsThis time-series analysis was based on prescription data from Apr. 1, 1996, to Mar. 31, 2012, obtained from the Drug Product Information Network database of Manitoba. We obtained sociodemographic information on benzodiazepine and Z-drug users from the Population Registry and determined changes in utilization rates over time using generalized estimating equations.

resultsOverall, the prevalence of benzodiazepine use remained stable at about 61.0 per 1000 population between 1996/97 and 2011/12; however, the prevalence of Z-drug use increased steadily from 10.9 to 37.0 per 1000 over the same period. In older people (≥ 65 years), the incidence of benzodiazepine use decreased from 55.5 to 30.3 users per 1000, whereas the incidence of Z-drug use increased from 7.3 to 20.3 users per 1000 over the study period. Among those 18-64 years of age, the incidence of benzodiazepine use decreased from 30.1 to 27.6 users per 1000, but the increase in incidence of Z-drug use was more than 2-fold. The youngest population (≤ 17 years) showed the lowest rates of use of these drugs. The highest rates of use were observed among older women and the low-income population.

interpretationOver the study period, benzodiazepines have been prescribed less frequently to older patients in Manitoba; however, zopiclone prescribing has continued to increase for all age groups. The reasons for this increase remain to be determined.
