  1. ref represent the reference category
  2. MAD minimal anxiety disorder, * MAD mild anxiety disorder, **MAD moderate anxiety disorder, SAD severe anxiety disorder, POR is proportional odds ratio from the ordinal logistic regression where SAD was taken as the key outcome with reference to MAD
  3. * MAD, and ** MAD, **** indicates that confidence interval estimates from bootstrapping were not possible
