More medical professionals perceived withdrawal of therapy as akin to physician-assisted suicide or euthanasia than legal professionals or patients (P<.001). In contrast, more legal professionals perceived the legal status as unclear than medical professionals or patients (P<.001). The percentage of respondents who perceived withdrawal as legal did not differ significantly among the groups. The actual percentage for each group is listed above the respective bar.
