Wikipedia has a good summary of Dr. Parnia's study:

Ergo, an "objective test" exists to establish the verdicality of NDEs (hence, the existence of an immaterial soul), and so, in this case, absence of evidence is evidence of absence.

Quote:AWAreness during REsuscitation (AWARE) study
While at University of Southampton, Parnia was the principal investigator of the AWARE Study, which was launched in 2008.[13] This study which concluded in 2012 included 33 investigators across 15 medical centers in the UK, Austria and the USA and tested consciousness, memories and awareness during cardiac arrest. The accuracy of claims of visual and auditory awareness was examined using specific tests.[20] One such test consisted in installing shelves, bearing a variety of images and facing the ceiling, hence not visible by hospital staff, in rooms where cardiac-arrest patients were more likely to occur.[21] The results of the study were published in October 2014; both the launch and the study results were widely discussed in the media.[21][22][23]
A review article analysing the results reports that, out of 2060 cardiac arrest events, 101 of 140 cardiac arrest survivors could complete the questionnaires. Of these 101 patients 9% could be classified as near death experiences. 2 more patients (2% of those completing the questionnaires) described "seeing and hearing actual events related to the period of cardiac arrest". These two patients' cardiac arrests did not occur in areas equipped with ceiling shelves hence no images could be used to objectively test for visual awareness claims. One of the two patients was too sick and the accuracy of her recount could not be verified. For the second patient instead, it was possible to verify the accuracy of the experience and to show that awareness occurred paradoxically some minutes after the heart stopped, at a time when "the brain ordinarily stops functioning and cortical activity becomes isoelectric." The experience was not compatible with an illusion, imaginary event or hallucination since visual (other than of ceiling shelves' images) and auditory awareness could be corroborated.[24]
Ergo, an "objective test" exists to establish the verdicality of NDEs (hence, the existence of an immaterial soul), and so, in this case, absence of evidence is evidence of absence.
