3—Significant eye irritation and/or discomfort.
4—Strong eye irritation and/or discomfort.
5—Very strong eye irritation and/or discomfort.
6—Almost unbearable eye irritation and or discomfort.
Because participants were matched for gender and age, analyses primarily involved performance of paired t tests in order to compare passive smokers to nonsmokers. In cases involving dichotomized outcome variables, McNemars chi square test for matched pairs was performed. Preliminary analyses that included gender as a factor revealed this to be nonsignificant. Only analyses based on the sample as a whole are presented.
