Multiple regression analysis was performed: ∗p < 0.05, ∗∗∗p < 0.001. PDAS: Pain Disability Assessment Scale, BMI: body mass index, NRS: Numerical Rating Scale, PCS: Pain Catastrophizing Score, HADS: Hospital Anxiety and Depression Scale, AIS: Athens Insomnia Scale, β: standardized regression coefficient, and CI: confidence interval.
