Abbreviations: ICC, intraclass correlation coefficient; CSAMI, Cutaneous Sarcoidosis Activity and Morphology Instrument; SASI, Sarcoidosis Activity and Severity Index; PGA, Physician's Global Assessment.

Correlation between SASI component scores and PGA were not calculated since multiple SASI scores were provided per patient.
