In Reply Dr Engdahl and colleagues state that the USPSTF “provides an ill-founded picture of the balance between benefits and harms of atrial fibrillation screening” and that our assumptions about the potential harms are not consistent with the data from screening trials. First, the recommendation is an “I” statement.1 The assignment of an “I” means that the evidence is insufficient to reach a conclusion about the balance of benefits and harms of screening for atrial fibrillation with ECG.
