From: Evaluation of pre-hospital transport time of stroke patients to thrombolytic treatment
Box plot of the alarm-to-door time in minutes and postal code areas. Area 1: <10 km from stroke centre, area 2: 11–30 km from stroke centre, area 3: 31–50 km from stroke centre, area 4: >50 km from stroke centre. NA represents a group where the pick-up location could not be determined. The NA group does not differ significantly from postal area group 1. Note the difference between group 3 and 4 (see Discussion).
