Correction: Using Canadian Primary Care Sentinel Surveillance Network data to examine depression in patients with a diagnosis of Parkinson disease: a retrospective cohort study ================================================================================================================================================================================ An earlier version of this article (published online Aug. 8, 2016) contained a typographic error in the Introduction.1 The last sentence in the Introduction read: "Existing studies on depression treatments in general have shown that women are more likely to have higher rates if medication use for treating depression given the higher prevalence of both depression diagnosis and use of primary care among women." The amended sentence should read as follows (with the correction in italics): "Existing studies on depression treatments in general have shown that women are more likely to have higher rates *of* medication use for treating depression given the higher prevalence of both depression diagnosis and use of primary care among women." *CMAJ Open* apologizes for any confusion this error may have caused. *CMAJ Open*** 2016.
