^*Antemortem samples for death investigations were collected in hospital prior to death.

^aOnly one postmortem blood sample was not femoral blood—a heart blood sample with an etizolam concentration of <5 ng/mL.

^bOne case excluded from statistical analysis because the concentration of etizolam was reported as >160 ng/mL.
