This table includes only participants who completed scales at both baseline and outcome.
* Determined by one-way ANOVA.
† Determined by Kruskal Wallis test.
‡ P < .001 for change in use between baseline and outcomes (Wilcoxon signed rank test). This measure required the respondent to have seen patients in the past 30 days both at baseline and outcomes assessments.
# P < .001 for change between baseline and outcomes (paired samples t test).
^ N = 780 for these determinations. P < .001 for change in use between baseline and outcomes (Wilcoxon signed rank test)
