Predictive validity of Lupus Patient-Reported Outcome for damage accrual in patients with systemic lupus erythematosus: the LUNA Registry

The predictive validity of disease-specific quality of life (QOL) remains unknown in patients with systemic lupus erythematosus (SLE), although disease-specific measures are equally or more responsive to changes than generic QOL. We aimed to examine the predictive validity of the Lupus patient-reported outcome (PRO) for damage accrual.
