Estimates of the crude and adjusted mean differences in the total evaluation time and total exposure time in minutes between the telemedicine and conventional groups.

^aThe conventional group estimate was subtracted from the telemedicine group estimate.

^bThe model was adjusted for age, gender, triage level, educational status, and primary care physician level.
