The Alopecia Areata Investigator's Global Assessment (AA-IGA ™) Scale: A Measure for Evaluating Clinically Meaningful Success in Clinical Trials.

CONCLUSIONS: We recommend the use of the SALT to assess the extent (0-100%) of scalp hair loss. Using the SALT assessment, the AA-IGA™ is a robust ordinal measure providing distinct and clinically meaningful gradations of scalp hair loss that reflects patients' and expert clinicians' perspectives and treatment expectations.
