Effects of ROI measures on anxiety as a function of age. Anxiety scores are adjusted for scanner, GAFs, gender, and all interactions between ROI measures, age, and gender. It is also adjusted for total cortical area in the VMPFC surface area model. Slopes for younger and older participants were computed at the first and third quantile for age, respectively. VMPFC surface area units are expressed in terms of mean partial membership-weighted voxel expansion factors. Mean cortical thickness units are in mm. a The relationship between VMPFC surface area and anxiety scores in younger vs. older participants. b The relationship between mean cortical thickness and anxiety scores in younger vs. older participants
