  • For each scenario, the respondents’ free-text answers were categorized to the single best-fit label from those listed here. The survey had a total of 377 respondents.

  • a SUID (includes sudden or unexpected, but not syndrome).

  • b Undetermined/unknown: undetermined, unknown, or uncertain.

  • c Pending/defer to pathologist: pending, needs more info, and defer to pathologist.

  • d Explained (not suffocation): pneumonia, other pulmonary conditions, and other causes.
