    • 1 (Minimal): Occasional fine scale over <5% of lesions, faint erythema, minimal plaque elevation;
    • 2 (Mild): Fine scale dominates, light red coloration, mild plaque elevation;
    • 3 (Moderate): Course scale dominates, moderate red coloration, moderate plaque elevation;
    • 4 (Marked): Thick non-tenacious scale dominates, bright red coloration, marked plaque elevation;
    • 5 (Severe): Very thick tenacious scale predominates, dusky to deep red coloration, severe plaque elevation.

    The DLQI questionnaire asks participants to evaluate the degree that psoriasis has affected their quality of life in the last week, and includes the following parameters: symptoms and feelings, daily activities, leisure activities, work or school activities, personal relationships and treatment related feelings. Participants answer 10 questions on a scale from 0 (not at all) to 3 (very much); the range of the total score is 0 to 30. A score of 21 to 30 means an extremely large effect on the participant's life whereas 0-1 means that the disease has no effect at all. A negative change from Baseline indicates improvement.
