Pairwise comparisons that were significantly different from one another are indicated as follows: when 2 values within a row do not share a common superscript, they are significantly different, whereas when 2 values within a row do share a common superscript, they are not significantly different. Significance (P < .05) determined by Mann–Whitney test for median and Wald test for proportions.
