↵* Multivariable, multilevel logistic mixed-effects regression model, with levels for emergency department visit, patient and facility. Models adjust for patient age, patient sex, comorbidities, area income, distance between patient residence and nearest hospital, mode of arrival (i.e., by ambulance or not), facility type presented to and zone of patient residence.
