  1. Data are given as median and interquartile range (IQR) or absolute numbers and percent. ‘Post ROSC’ designates the group of patients in which NIRS was started shortly after ROSC, ‘pre ROSC’ designates the group with NIRS started during CPR and who achieved ROSC, ‘no ROSC’ the group with NIRS during CPR but no ROSC.
