  1. The number of observations, percentage shown in parentheses (%), and the respective P-values are shown resultant from Pearson's χ2-test of association (χ2), or Fisher's exact test, in which the frequency of observations in a cell was less than 5 (indicated with *). Statistically significant P-values are indicated by bold font.
