Fig 5. Modification of times from ambulance contact to hospital arrival and first-drug administration.

The square box indicates no adjustments. The two ends of the color spectrum show a 6% increase and decrease in predicted CPC1/2, respectively. Overall, reducing the time for hospital arrival improved outcomes, whereas delays worsened them. Reducing the time to drug administration strengthened the effect of reducing the transport time, but reducing the transport time improved the prognosis even with delayed drug administration. CPC, cerebral performance category.
