Data are number (%). CI: confidence interval, CVD: cardiovascular disease, N: number, n/a: not applicable, OPD: obstructive pulmonary disease, OR: odds ratio.1Use of β- adrenoreceptor blockers, calcium channel antagonists, angiotensin converting enzyme inhibitors, diuretics, angiotensin-II receptor blockers, nitrates, platelet aggregation inhibitors, and/or statins within six months prior to index date.2Adjusted for cardiovascular risk profile.3Interaction on a multiplicative scale: OR 1.1 (0.7–1.6), on an additive scale: synergy index 1.4 (0.7–2.6).
