Nonprescribed use of tranquilizers or sedatives by adolescents: a Brazilian national survey.
Article in BMC public health, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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
backgroundAlthough the nonprescribed use of tranquilizers or sedatives by adolescents is a cause for concern in many countries, there is a shortage of data from low and middle income countries (LAMIC). The present study aims to estimate the prevalence of nonprescribed use of tranquilizers/sedatives by adolescents in Brazil, and to assess how socioeconomic and demographic circumstances, as well as indicators of access to these substances are associated with their use and with risk perception.
methodsA cross-sectional study was conducted using a multi-stage probability sample of 18131 high school students from public and private schools from all 27 Brazilian state capitals. A self-reporting questionnaire was used to obtain information on social and economic circumstances, nonprescribed use of tranquilizers or sedatives and risk perception of their use.
resultsLifetime nonprescribed use of tranquilizers or sedatives was reported by 5% of respondents, more commonly among females (OR: 2.19, 95% CI: 1.75-2.75) and those attending private schools (OR: 1.47, 95% CI: 1.17-1.84). The use of tranquilizers/sedatives by relatives or friends was associated with nonprescribed use by the participant (OR: 4.26, 95% CI: 3.46-5.23) and a majority of lifetime users obtained these substances from a family environment (82%). Previous medical prescription was independently associated with nonprescribed use (OR: 6.61, 95% CI: 4.87-8.98) and with low risk perception (OR: 2.42, 95% CI: 1.12-5.24).
conclusionsA substantial proportion of Brazilian adolescents use nonprescribed tranquilizers/sedatives. Easy access to these substances seems to play an important role in this use and should be tackled by preventive and treatment interventions.
