Finally, analyzing the data cumulatively across the different vignettes may have introduced variability in the data and be a potential limitation. We elected to do this because of the nonsignificant differences found between the vignettes and because aggregating the data allowed for a larger sample and more parsimonious analysis. However, it is possible that differences between groups would be observed with a larger sample size, and with this larger sample, analyzing the results between groups separately may be meaningful.
