This is an example showing the representation of data from a PGI relating to psoriasis improvement. This assessment was based on a 5-point scale (0 = Worse, 1 = No Change, 2 = Somewhat Better, 3 = Better, and 4 = Much Better). As in Example 1, data were represented in the QS domain following the QRS Supplement: Patient Global Impression (PGI).
Note that original result was standardized to the numeric value in QSSTRESC.
