Occurrence of out-of-hospital cardiac arrest (OHCA) and 1-month survival after OHCA by hour of the day. There were temporal differences in OHCA occurrence with a bimodal distribution; OHCA less frequently occurred at night (2301–0700 h, 2.7 % hourly, average of 8 h) compared to daytime (0701–1500 h, 5.0 % hourly) and evening (1501–2300 h, 4.8 % hourly). Patients with daytime OHCA had a 1-month survival rate of 7.6 %, patients with evening OHCA had a 1-month survival rate of 5.0 %, and patients with nighttime OHCA had a 1-month survival rate of 4.9 %
