In Chinese criteria, repeated tests should be done 12 h after the first evaluation. The items “repeat test” represented the second evaluations. “Done” means the selection rate of the test in all 37 patients. “Complete” means the finishing rate of the test in all patients who had done the test. “Positive” means the positive rate of the test in all patients who had completed the test. TCD: Transcranial Doppler; EEG: Electroencephalogram; SEP: Somatosensory evoked potential; BD: Brain death.
