Disease characteristic measures which are determinants of Health-related Quality of Life in 201 patients with cervical dystonia. Health-related Quality of Life (HrQoL) assessed by the Cervical Dystonia Impact Profile−58 (CDIP-58) and the EuroQoL Utility Index. Correlations (r-squared) between these HrQoL measures with patient reported levels of TWSTRS-2 Pain, TWSTRS-2 Disability, the physician-assessed TWSTRS-2 Severity; also, the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI-II). Significant correlations, surviving multiple variable analysis, are in bold
(* < 0.05; ** < 0.01; *** < 0.001; **** < 0.0001) (TWSTRS, Toronto Western Spasmodic Torticollis Rating Scale).
