The survival rate from the cardiac arrest events in the study was 16% (330 from 2060). The mean age of the patients was 64.
39% of the survivors claimed to have a recollection of some sort of experience during the event. 9% of these could be classified as NDEs defined by the Greyson scale. This is consistent with other findings in other survey studies.
Only 22% of cases took place in the specifically set up test surrounds. The majority of arrests and resuscitations took place in areas without the orchestrated visual stimuli present.
Of the 2060 cases recorded, only 2 patients reported an apparent OBE visual experience of occurring events. Only one of these patients was well enough for follow up interviews for veridical validity examination of their recollection. (0.05% of the study group)
The single case validated by the paper appears to be an accurate veridical recollection of events, both visually and audibly by the patient whilst suffering a cardiac arrest and in a Glasgow Coma scale of 3/15, up to within 3 minutes of this condition. It took place outside of the experiment test areas, so no specifically orchestrated test stimuli were present, either visual or audio. The validation was asserted based on anecdotal records.
