Note: OR = odds ratio; CI = confidence interval; p = p-value; crude ORs were derived from univariate nonconditional logistic regression; adjusted ORs were adjusted for all variables in the table; ADDI-PA = Positive Affect from the Anxiety Depression Distress Inventory–27; ADDI-SA = Somatic Anxiety from the Anxiety Depression Distress Inventory–27.
