Percentage of Participants Who Experienced Psoriasis Relapse
Psoriasis Area and Severity Index (PASI) is a combination of the intensity of psoriasis, assessed by the erythema (reddening), induration (plaque thickness) and scaling on a scale range from 0 (no symptoms) to 4 (very marked), together with the percentage (%) of the area affected, rated on a scale from 0 (0%) to 6 (90-100%). PASI scoring is performed at four body areas, the head, arms, trunk, and legs. The total PASI score ranges from 0 (no psoriasis) to 72 (the most severe disease). Relapse is defined using the following thresholds: PASI greater than (\>) 3 (participants who had a PASI lesser than or equal to \[\<=\] 3 at baseline); PASI \> 5 (participants who had a PASI \<= 5 at baseline); DLQI \> 5 (participants who had a DLQI \<= 5 at baseline); Initiation of any topical drug/medication for psoriasis; Initiation of any systemic therapy for psoriasis (biologic or non-biologic).

Absolute Body Surface Area (BSA) Scores
The BSA is a numerical score used to measure the total area of the body affected by psoriasis. The palm method will be applied: the participant's palm, including the five digits is used as a reference (representing approximately 1% of the total body surface area) and is used to repeatedly cover the lesions on the body. The investigator totals the number of palms required and then estimates the percentage (%) in each of the four body regions: head (including scalp) and neck (10%); upper extremities (20%); trunk (30%); and lower extremities (40%).

Each item is scored from 0 (not affected at all) to 3 (very much affected). The DLQI score is the sum of the 10 individual question scores and ranges from 0 (no effect at all on participant's life) to 30 (extremely large effect on participant's life), with lower scores indicating better quality of life.
