Statistical Analysis
Descriptive statistics were used to summarize all baseline demographic and outcome variables. Differences in the distribution of responses across the four scenarios was tested using Cochran’s Q test. In the event that this test was significant at the two-sided 0.05 level, all pairwise comparisons (n=6) of the results from the 4 scenarios were made using McNemar’s test while testing at a Bonferroni-adjusted 0.05/6 = 0.0083 level.
