About Dataset

These data has been collected by RVI in Newcastle. Patients undergo UVB treatment for psoriasis in the clinic, 3 times a week for 9-12 weeks. For each patient, at the beginning of the therapy and every Friday during treatment, clinicians recorded the Psoriasis Area Severity Index (PASI). PASI ranges over 0-72, with 0 meaning normal, psoriasis-free skin. The goal of the therapy is to bring the PASI reading down to 0, or thereabouts.
