We included 404 (28%) patients who were in an unresponsive state as assessed by the ACDU scale at the time of on-call consultations to the NAT; and excluded 190 patients who either did not have QP measurements due to NAT activation during after-hours (n = 129), showed unresponsiveness following cardiac arrest (n = 46), or had incomplete demographic data (n = 15). Here, BRD2 is linked to cardiac arrest.
