A quantitative bias analysis of the association between supervised consumption service use and sharing of injection equipment among people who inject drugs in Toronto, Canada
In summary, SCS use was not associated with equipment sharing in a context of high needle and syringe program coverage. Misclassification, selection bias, and unmeasured confounding did not appear to impact the observed associations.
