Figure 3.

Impact of reducing door to needle time. Map shows Ireland broken into 139 regions with geographic centres plotted. Door to needle time is reduced to 30 min, time from alteplase administration to departure for the endovascular thrombectomy (EVT) centre is 60 min, door to groin puncture time is 100 min in the mothership scenario and 10 minutes in the drip-and-ship scenario. Panel A displays one EVT centre; panel B shows two EVT centres. Regions are colour coded to show the method predicting the best probability of good outcome.

DIDO: door-in-door-out; DTN: door to needle; DTP: door to puncture.
