Most of the AAS users in this study were recreational exercisers who practiced polypharmacy. The AAS users were more likely than nonusers to meet criteria for substance dependence disorder, report a diagnosis of an anxiety disorder, report recent cocaine use, and have a history of sexual abuse. The information uncovered in this study may help clinicians and researchers develop appropriate intervention strategies for AAS abuse.

Patients admitted to an ICU on the weekend have a modestly higher risk for death and ICU length of stay. However, the similar risk for death in patients admitted on Friday and Monday suggests that "weekend effects" may be more related to unmeasured severity of illness and/or selection bias than to differences in quality of care.
