Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To elicit the trade-offs that vitiligo patients make when treatment is clinically indicated and thus identify the weighting of characteristics of a treatment (preferences). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary objectives are benefit-risk assessment to estimate patient maximum level of acceptable risk of treatment-related sides effects, the overall comparison to assess the relative importance of attributes and adherence to identify key attributes that affect patients’ willingness to adhere to topical treatment options. Exploratory objectives are the analysis of heterogeneity to assess how preferences differ based on respondents' characteristics and the identification of personas or subgroups to explore and explain heterogeneity based on the correlation between preferences and sociodemographic information, experience-based treatment history and attitudes of the respondents. | — |
