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.
