Effects of anabolic androgenic steroids on sleep patterns of individuals practicing resistance exercise.
Article in European journal of applied physiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Anabolic androgenic steroid (AAS) abuse has become a public health problem in many countries, and is associated with many psychiatric disorders. Epidemiological studies have also found increasing numbers of sleep disorders reported by individuals using AASs. The purpose of this study was to evaluate sleep patterns and disorders in anabolic androgenic users who practice resistance exercise. The sample comprised 58 males divided into three groups: (1) 20 current AAS users aged 26 +/- 1.2, (2) 21 controls with no history of AAS use, aged 26 +/- 1 and (3) 17 sedentary men with no sleep disorders aged 27.2 +/- 0.34. The volunteers spent a night in the sleep laboratory for polysomnography. Comparing the three groups, the user group showed reduced sleep efficiency and more wakings after sleep onset than the sedentary group (P = 0.001). The sedentary group showed a higher percentage of stage 4 than the non-users group. We suggest that using of anabolic steroids reduced sleep efficiency and alters sleep architecture.
