  2. Values are percentages (nominator/denominator) or means ± standard deviations (denominator).
  3. Denominators vary due to missing individual answers.
  4. * denotes .01 <= P < .05; ** denotes .001 <= P < .01; *** denotes P < .001; P-values are based on Fisher's exact test (binary variables) and t-test (continuous variables).
