Fig. 2From: Supraventricular arrhythmia, N-terminal pro-brain natriuretic peptide and troponin T concentration in relation to incidence of atrial fibrillation: a prospective cohort studyIncidence rates (95% confidence intervals) of AF in relation to a combination of elevated NT-proBNP and frequent SVEs stratified by elevated CHARGE-AF score. Frequent SVEs and elevated NT-proBNP were defined as the top quartile, corresponding to > 129.18 SVEs/24 h and 32.80 pg/ml NT-proBNP, respectively; elevated CHARGE-AF score was defined as top tertile.
