  • Percentage change in reported sunburns for each category is based on the paired observations from baseline and follow-up evaluations.

  • a P value based on the paired comparison from baseline to follow-up evaluation. For dichotomous variables, the McNemar test was used. For variables with 3 or more categories, the Stuart-Maxwell statistic was calculated.
