Adjusted risk of incident depression according to physical activity status among systemic lupus erythematosus patients^*

	HRadj (95% Cl)†
Physically active	1 (−)
Physically inactive	3.88 (1.67–9.03)

^*Among the 225 patients eligible for inclusion in the multivariable analysis, 22 had missing data for ≥1 of the covariates (e.g., income), resulting in n = 201 for the adjusted model. 95% Cl = 95% confidence interval; HR_adj = adjusted hazard ratio.

^†HR_adj obtained from the Cox proportional hazards model adjusted for age, sex, race, income, comorbidities (cardiovascular disease, diabetes mellitus, asthma, malignancy), disease activity by the Systemic Lupus Erythematosus Disease Activity Index, and disease damage by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index.
