Graphical representation of three-way interaction showing adjusted hazard ratios all-cause mortality (ACM) for persons using compared to those not using selected antihypertensive agents in a given week
HR_ABCs_ACM = adjusted hazard ratios (HR) for all-cause mortality (ACM) based upon exposure to renin angiotensin system antagonists, β-adrenergic blockers, and/or calcium channel blockers (ABCs)
Three-way interaction terms include 1) exposed compared to not exposed to selected antihypertensive in a given week, 2) proportion of prior weeks exposed (cumulative exposure %), and 3) number of switches between exposed and not exposed weeks.
Red depicts higher hazard ratios (> 1.0) while blue depicts lower hazard ratios (< 1.0).
