of researchers. During the next decade prospective studies were also starting to emerge from other parts of the world. In a study from 2010 Klemenc-Ketis and colleagues reported on out-of-hospital cardiac arrest survivors, later admitted to intensive care units, at medical centers in Slovenia. 21.2% of the patients in the study reported NDEs. The researchers also found that "NDE occur more often in patients with higher petCO2 and pCO2"; "higher serum levels of potassium correlate with higher score on Greyson’s NDE scale"; and "NDEs occur more often in patients with previous NDEs". Recently, the work of Jeffrey Long has also attracted attention to the topic of NDEs in both the academic, and the popular field. Long is a near death experience researcher who believes in life after death. In 2010 he released a book, co-authored with Paul Perry, called Evidence of the Afterlife: The Science of Near-Death Experiences. In the book Long presented results from research conducted over the last decade. Based on the results from an analysis of scholarly NDE-related periodical literature, the decade between 2001 and 2011 signalled an expansion of the field of Near-death studies by including new authors and new publication venues. Research has also entered into other fields of interest, such as the mental health of military veterans. Goza, Holden & Kinsey studied NDEs among combat veterans. They found, among other things, that combat soldiers reported "less intense" near-death experiences, compared to NDErs in the civilian population. The first clinical paper from The AWARE-project (AWAreness during REsuscitation), another prospective study, was published in 2014. The research was a multicenter observational study including US, UK and Austrian medical sites. In the study Parnia and colleagues found that 9% of patients who completed stage 2 interviews reported experiences compatible with NDEs. A follow-up study, the AWARE II, is currently being conducted, and results have started to appear. In a study from 2020 Charland-Verville and colleagues studied the near death experiences of 158 participants through text mining. This study found that analyzing these experiences by the way participants explain them through speech can allow researchers to understand even more about NDEs, rather than just relying on the memories and self-reports of participants, which are less confidential than scientific evidence. It was also proven that non-verbal communication like gestures and emotions can allow researchers to further understand NDEs and their heavy effect on people who have had them. Psychometrics
