a,bValues 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. Tests are adjusted for all pairwise comparisons within a row of each innermost subtables using the Bonferroni correction.
