*Cox proportional hazards models were weighted using a propensity score model by the IPTW method adjusted for age, sex, SES, Charlson comorbidities and use of other medications (insulin, ACEi, ARB, beta-blockers, CCB, diuretics and statins) at baseline, defined as a prescription within 1 month before or after diagnosis.

ACEi, ACE inhibitor; ARB, angiotensin receptor blocker; CCB,  calcium channel blocker; IPTW, inverse probability of treatment weighted; SES, socioeconomic status.
