Real-world effectiveness of lipid-lowering medications on outcomes after stroke: potential implications of the new-user design

Introduction: Observational studies are increasingly being used to provide evidence on the real-world effectiveness of medications for preventing vascular diseases, such as stroke. We investigated whether the real-world effectiveness of treatment with lipid-lowering medications after ischemic stroke is affected by prevalent user bias. Methods: An observational cohort study of 90-day survivors of ischemic stroke, using person-level data from the Australian Stroke Clinical Registry (2012-2016; 45 hospitals) linked to administrative (pharmaceutical, hospital, death) records. Use of, and adherence to (proportion of days covered
