The consensus method of selecting the indices to include and the classification of real patient profiles by an expert panel to create a gold standard of severity were used. The performance of potential cut-offs was evaluated to create a ranking algorithm. The combined use of PASI, BSA, and sPGA may allow the classification of the severity of psoriatic patients. The final algorithm identifies severe patients in a single step (2 out 3 are met: PASI ≥ 11 or BSA ≥ 10 or sPGA ≥ 3), while two steps are required for mild ((2 out 3 are met: PASI ≤ 3 or BSA ≤ 5 or sPGA ≤ 2) and DLQIenAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/classificationcut-offsdiscriminationmoderatepsoriasisseverityresearch article34209585open access10.3390/life11070627PMC8307918https://www.mdpi.com/2075-1729/11/7/627/pdf?version=1624952531https://pmc.ncbi.nlm.nih.gov/articles/PMC8307918/pdf
