Determinants of risk of sudden cardiac arrest.

CI: confidence interval, OR: odds ratio. 1Adjusted for all potential confounders. 2Adjusted for all covariates that were univariately associated with sudden cardiac arrest. 3Adjusted for all covariates that were univariately associated with sudden cardiac arrest and changed the beta with at least 5%. 4Use of any of the following drugs: 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. 5Use of anti-diabetics within six months prior to index date. 6Class I and III antiarrhythmic drugs and non-antiarrhythmic drugs with (possible) risk of QT prolongation.
