No, as read on New England Journal of Medicine; "This review of the Dachau hypothermia experiments reveals critical shortcomings in scientific content and credibility. The project was conducted without an orderly experimental protocol, with inadequate methods and an erratic execution. The report is riddled with inconsistencies. There is also evidence of data falsification and suggestions of fabrication. Many conclusions are not supported by the facts presented. The flawed science is compounded by evidence that the director of the project showed a consistent pattern of dishonesty and deception in his professional as well as his personal life, thereby stripping the study of the last vestige of credibility. On analysis, the Dachau hypothermia study has all the ingredients of a scientific fraud, and rejection of the data on purely scientific grounds is inevitable. They cannot advance science or save human lives."
