CMA-M—census metropolitan area of Montreal, CVD—cardiovascular disease, ICD—International Classification of Diseases.

^*A patient was considered to be at risk of CVD if he or she had received a primary or secondary diagnosis of hypertension (ICD-9 code 401, ICD-10 code I10), diabetes (ICD-9 code 250, ICD-10 code E10–E14), or dyslipidemia (ICD-9 code 272, ICD-10 code E78) during a hospitalization or at least 3 physician claims within 1 y with an identical diagnosis.

^†A patient could be present in more than 1 disease-specific cohort (eg, a patient with hypertension could also have diabetes).
