Summer 2021 Meta-Analysis Report
The second quarter 2021 issue of Cryonics includes a report on Alcor Case Metrics 2000-2020. This begins with a selection of case data for the years of 2019 and 2020 followed by a look at the 141 cases in the 21-year period from 2000 to 2020. (2000 was picked as the starting point because that year saw the introduction of vitrification technologies at Alcor.)
It’s not uncommon to find people on the internet making claims about the percentage of cases that are straight freezes, or that involve autopsies, and so on. Sometimes these lack any support and at other times the evidence is limited. The meta-analysis makes it possible to examine these numbers objectively and as accurately as possible.
For instance, in the 21 year period 2000 to 2020, 6% of cases involved an autopsy, 13 or 14% involved unattended deaths, and 23% were straight freeze. Cardiopulmonary support was provided in 66% of cases, cryoprotective perfusion was achieved in 77%, and (so far) 10% of cases have been “field cryopreservation”
See the accompanying article, “Alcor Case Metrics: Scope and Comments” by Aschwin de Wolf and Michael Benjamin for thoughts on the usefulness of the meta-analysis results. Although some factors influencing the quality of outcomes is very hard for a cryonics organization to control, none should be considered completely outside the realm of influence. This analysis helps to show where to focus our efforts. The next step in this project is to identify trends and correlation.
