Misclassification rate on excluded subset (%)	27	28	28	27	27	29	28	30	27	26

+ means that a variable has been included in the model. Subset (excluding) 1 means all patients included except those in subset 1. Subset 1 was used to calculate a misclassification rate for model 1, etc.
AF, atrial fibrillation; ARA, aldosterone receptor agonist; HF, diagnosis of heart failure; LVSD, left ventricular systolic dysfunction.
