Figure 2. PASI and DLQI. (A) Psoriasis Area and Severity Index (PASI) comparison between usual care and dose reduction. PASI scores (median and IQR) are depicted for the original CONDOR study (month 0, 3, 6, 9 and 12) and for the CONDOR extension phase (month 15, 18, 21, 24). Significant differences were seen at 9 months (p = .005), at 12 months (p = .001), at 15 months (p = .002) and at 18 months (p = .003). (B) Dermatology Quality and Life Index (DLQI) depicted for the original CONDOR study (month 0, 3, 6, 9 and 12) and for the CONDOR extension phase (month 15, 18, 21, 24). Significant differences between dose reduction and usual care were only observed at 6 months (p = .005). No significant differences were observed in the extension period. *Significant differences that were observed between dose reduction and usual care.
