Generalized anxiety disorder (GAD) is commonly accompanied by depressive symptoms, sleep disturbance, and somatic symptom burden, which may influence treatment selection and real-world outcomes. This retrospective cohort study evaluated the comparative effectiveness and tolerability of Huatan Jieyu Formula (HTJYF) versus paroxetine in adults with GAD treated at a single institution between September 2023 and December 2024. Eligible patients received an 8-week course of HTJYF (n = 38) or paroxetine (n = 40). Anxiety severity was assessed using the Hamilton Anxiety Rating Scale (HAMA) and the Generalized Anxiety Disorder 7-item scale (GAD-7). Secondary measures included the 17-item Hamilton Depression Rating Scale, Pittsburgh Sleep Quality Index, and Patient Health Questionnaire-15. Baseline characteristics were broadly comparable between groups. Both treatments were associated with significant within-group reductions in HAMA and GAD-7 scores from baseline to week 8 (all P < .001), while between-group differences in anxiety improvement were not statistically significant (HAMA change: 1.21 points, 95% confidence interval - 0.45 to 2.87, P = .151; GAD-7 change: 0.90 points, 95% confidence interval - 0.26 to 2.06, P = .125). Improvements in depressive symptoms and somatic symptom burden were similar between groups, whereas sleep quality improved slightly more with HTJYF (Pittsburgh Sleep Quality Index ΔΔ = 0.90, P = .045). Treatment-emergent adverse events occurred at comparable r...
