Dose–response relationship between risk of CVD events with systolic blood pressure, diastolic blood pressure as well as pulse pressure as continuous variables in the treated and untreated populations. In the treated population, the relationship was linear for SBP (a), U-shaped for DBP (b) and linear for PP (c). In the untreated population the relationship was linear for SBP (d), U-shaped for DBP (e) and linear for PP (f)
