Human experiments were more extensive than often assumed with a minimum of 15,750 documented victims.

Experiments rapidly increased from 1942, reaching a high point in 1943 and sustained until the end of the war.

There were more victims who survived than were killed as part of or as a result of the experiments. Many survived with severe injuries.

Victims came from diverse nationalities with Poles (Jews and Roman Catholics) as the largest national cohort.

Body parts, especially from euthanasia killings, were often retained for research and teaching after 1945.
