Time to Improvement From Baseline (Week 0) in PASI Score
Time to improvement from baseline in PASI (PASI 75/90/100 response and absolute PASI score =0) for participants with short disease duration (SDD) (less than or equal to [<=] 2 years) and longer disease duration (LDD) (greater than [>] 2 years) was reported. PASI was a system used for assessing and grading severity of psoriatic lesions and their response to therapy. In PASI, body was divided into 4 regions: head, trunk, upper extremities, and lower extremities. Each of these areas was assessed separately for percentage of area involved, which translates to numeric score that ranged from 0 (indicated no involvement) to 6 (90%-100% involvement), and for erythema, induration, and scaling, which were each rated on a scale of 0 to 4. PASI produced a numeric score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated more severe disease. PASI 75/90/100 responders were defined as participants with >= 75%, >= 90%, 100% improvement in PASI respectively.

Change from baseline in NAPPA-PBI at Weeks 28, 68, 116, 164 and 220 will be reported. The NAPPA was an instrument for assessing clinical and patient-reported outcomes in nail psoriasis. NAPPA-PBI was a 24-item questionnaire to assess participant-defined needs before and participant-rated benefits after treatment. The answers were given on a scale from 0 to 4, and a global score was calculated as follows: Each benefit item was multiplied with the respective importance item, and the product is divided by the sum of all importance items. The results were summed up over all items. The resulting global score ranged from 0 (no benefit) to 4 (highest possible benefit). Higher score indicated more benefit.
Groups 1, 2a, 2b, 2c, 3a and 3b: Change From Baseline in Nail Assessment in Psoriasis and Psoriatic Arthritis- Clinical (NAPPA-CLIN) at Weeks 28, 68, 116, 164 and 220
Change from baseline in NAPPA-CLIN at Weeks 28, 68, 116 164, and 220 will be reported. The NAPPA is an instrument for assessing clinical and patient-reported outcomes in nail psoriasis.

Two sub scores each ranging from 0 to 100 were derived: the psoriasis symptom score and the psoriasis sign score. A higher score indicated more severe disease. A change of >= 40 points in PSSD symptom score or sign score, and a >= 3-point change in individual PSSD item scale scores will be defined as clinically meaningful change (response).

Group 1, Group 2a, Group 2b and Group 2c: Relationship Between Trough Serum Concentration and Efficacy or Serum Biomarker Level
The potential association between trough serum guselkumab concentration and efficacy or serum biomarker level will be analyzed by immunoassays. For the analyses the trough serum guselkumab concentration will be set into relation with the efficacy (e.g. PASI response) or with serum biomarker (e.g. serum IL-17A, IL-17F, IL-22) concentration. Guselkumab and all biomarker concentrations will be measured in the unit of picogram/milliliter (pg/mL). In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 (indicates no involvement) to 6 (90%-100% involvement), and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72. A higher score indicates more severe disease.
Group 2a and Group 2b: Relationship Between Trough Serum Guselkumab Levels at Weeks 20, 28, 36 and 68 and Achieving PASI Score <3 at Week 68

Group 1, Group 2a, Group 2b, Group 2c, Group 2d, Group 3a, Group 3b, and Group 3c: Number of Participants With Adverse Events as a Measure of Safety and Tolerability
An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product.
