Table 2. Demographic data and prevalence of REM sleep intrusion.
To adjust for multiple testing, the alpha level was set to 0.01. Significant p values are shown in bold script. N, number of participants; NDE, near-death experiences; REM, rapid eye movements; SD, standard deviation; *when comparing “No NDE” (n = 744) with confirmed near-death experiences with a Greyson NDE Scale score ≥ 7 (n = 106; see Table 3), this significance is lost (p-value = 0.256).
