Figure 1. Subject flow chart in the case and control groups.
IHCA: in-hospital cardiac arrest; OHCA: out-of-hospital cardiac arrest.

Figure 2. Proportion of potential corneal donors in each setting of death. Individuals who experienced OHCA or IHCA were treated at Hiroshima City Hiroshima Citizens Hospital, and individuals who died at home were treated at Fukui Internal Medicine Clinic. We did not include subjects who donated corneas in each setting of death.
These proportions among the three settings of death were compared using the χ²-test.
IHCA: in-hospital cardiac arrest; OHCA: out-of-hospital cardiac arrest.
