n = number of patients with/without the specified final diagnosis in any position in the specified population (Total, ECG, No ECG); % = percentage of patients in the specified population with/without the specified final diagnosis in any position
P<0.0001 for each chi-square test assessing the significance of a relationship between whether the specified final diagnosis is in any position and prehospital ECG use.
