Outcomes should reflect the above aims and will therefore most importantly address patient satisfaction with treatment and changes in disease-related quality of life. Outcomes should thus include proportions of patients reporting good or excellent response to treatment and reporting that treatment is "worthwhile". Similarly, proportions of patients achieving clearance or near clearance of disease are more robust outcomes than are absolute or relative changes in disease severity scoring systems such as the psoriasis area and severity index (PASI). Adverse effects and their frequency are equally important because they may limit the utility of otherwise effective interventions.
