Figure 2.

This figure presents the odds ratios and corresponding 95% confidence intervals (CIs) investigating the associations between baseline factors and the attainment of ≥ 90% improvement in Psoriasis Area and Severity Index (PASI) at 6 months. Estimates were obtained from a multivariable logistic regression analysis. Results for white ethnicity and skin type are estimated from a model excluding the other due to similarities in these two variables. Skin type was included as a continuous variable, where a higher value represents darker skin.
