Regression Analysis Showing the Significant Predictors of the MADRS at Baseline and at Week 8^ab

MADRS	BPI-SF Average Pain	SCL-90-R Obsessive-Compulsive	SCL-90-R Interpersonal Sensitivity	SCL-90-R Anxiety	SCL-90-R Phobic Anxiety	SCL-90-R Paranoid Ideation
Baseline	…	3.69	…	…	…	…
Week 8	4.06	3.92	2.57	2.64	–3.79	–2.67

^aThe t values from the linear multivariate regression model are displayed in this table; only t values that are significant at p ≤ .05 are listed.

^bCovariates taken into account were the following: all the SCL-90-R subdomains except SCL-90-R depressive domain, number of pains, and BPI-SF average pain.

Abbreviations: BPI-SF = Brief Pain Inventory-Short Form, MADRS = Montgomery-Asberg Depression Rating Scale, SCL-90-R = Symptom Checklist-90-Revised).
