Diagnoses were made considering the entire clinical record instead of CRS-R alone. MCS− indicates that patients display visual fixation and pursuit, automatic motor reactions (e.g., scratching, pulling bed sheet), or localization to noxious stimulation. MCS+ classification indicates that patients consistently and repeatedly followed simple commands or intelligibly verbalized (69, 70). Patients classified as MCS showed such behavior but only intermittently. CRS-R is the highest score recorded by the attending physician for the day of the scanning session. CRS-R scores were collected at least once on the day of scanning with periodic additional assessments on remaining visit days.
