  1. Data are Mean ± SD. The first number refers to the number of operating rooms running during daytime (0600–2200; 16 h) and the second number refers to the number of ORs running at night time (2200–0600; 8 h). The n in parentheses aside number of ORs refers to the number of simulation runs performed
