Primära resultatmått

Resultatmått
Åtgärdsbeskrivning
Tidsram
Change from baseline to week 4 of Clinician's Erythema Assessment (CEA)
Tidsram: Week 4
The CEA is a static 5-point grading scale of facial erythema severity. The scale is 0 to 4. A positive result, means that the erythema, redness was reduced. A negative result indicates that the erythema increased.
Week 4
Change from baseline to week 4 in the Dermatology Quality Life Index (DLQI)
Tidsram: Week 4
The DLQI is a dermatology-specific quality of life instrument to measure the impact of skin disease on different aspects of health-related quality of life. The questionnaire contains 10 questions, each scored on a 4-point Likert scale. The DLQI is calculated by adding the score of each question, resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired. A score higher than 10 indicates that the patient's life is being severely affected by their skin disease.

Week 4, Week 8
Change from week 4 to week 8 in Global Flushing Severity Score (GFSS) from baseline to week 4 & 8
Tidsram: Week 4, Week 8
The GFSS is a 0-10 numeric rating scale assessing facial flushing symptoms including redness, warmth, tingling, or itching over the past 24 hours, with scores ranging from: 0 (did not have), 1-3 (mild), 4-6 (moderate), 7-9 (severe), 10 (extreme).
Week 4, Week 8
Change from in Patient Health Questionnaire-9 (PHQ-9) scale from baseline to week 4 & 8
Tidsram: Week 4, Week 8
The PHQ-9 is a widely used tool for assessing depression severity, with scores ranging from 0 to 27 based on the frequency of symptoms over the past two weeks
Week 4, Week 8
Change in Generalized Anxiety Disorder-7 (GAD-7) scale from baseline to week 4 & 8
Tidsram: Week 4, Week 8
The GAD-7 evaluates anxiety severity with scores ranging from 0 to 21, using a similar structure to the PHQ-9. Scores are categorized as minimal (0-4), mild (5-9), moderate (10-14), and severe (15-21).
Week 4, Week 8
Change of Clinician's Erythema Assessment (CEA) scale from baseline to week 4 & 8
Tidsram: Week 4, Week 8
The CEA is a static 5-point grading scale of facial erythema severity. The scale is 0 to 4. A positive result, means that the erythema, redness, was reduced. A negative result indicates that the erythema increased.
Week 4, Week 8
DermSat-7 score at week 4 & week 8
Tidsram: Week 4, Week 8
The DermSat7 is a 7-item, self-administered questionnaire designed to assess patient satisfaction with dermatologic treatments. It covers three domains - effectiveness (3 items), convenience (3 items), and overall satisfaction (1 item) - with responses on a 5-point (or 5-point) satisfaction scale, then transformed into a 0-100 scale so that higher scores indicate greater satisfaction.
