Note: values in the same row and subtable not sharing the same subscript are significantly different at p < 0.05 in the two-sided test of equality for column proportions. Cells with no subscript are not included in the test. Tests assume equal variances.²

¹This category is not used in comparisons because its column proportion is equal to zero or one.

²Tests are adjusted for all pairwise comparisons within a row of each innermost subtable using the Bonferroni correction.
