From: A validation of ground ambulance pre-hospital times modeled using geographic information systems
Comparison of modeled and actual response and transport intervals. This figure shows the actual EMS response interval times in comparison to the modeled response times (top two scatterplots) and the actual EMS transport interval times in comparison to the modeled transport times (bottom two scatterplots). The red line represents the line of agreement. If EMS times are greater than the modeled times, they fall above the line of agreement.
