Note. MDD = current major depressive disorder; GAD = current generalized anxiety disorder; MDD-GAD = current major depressive disorder and generalized anxiety disorder; CTL = no past or current psychiatric disorder. Clinical group represents the estimate in the MDD, GAD, and MDD-GAD groups combined. CTL group contrast represents the difference between the estimates in the clinical group and the CTL group. Group differences are denoted only when they are statistically significant.
