Separate linear regression analyses were performed for each predictor variable. Model intercepts are not reported to simplify result interpretation. Binary predictor variables are termed in a way that makes dummy coding obvious (e.g. female sex: 0 = male, 1 = female). Abbreviation: HAMA Hamilton Anxiety Rating Scale. ^†Models were adjusted for respective (HAM-D or BDI) baseline symptom covariate
