231 Epidemiology of alopecia areata, totalis, universalis, and ophiasis: A systematic review and meta-analysis

Alopecia areata (AA) is a common autoimmune alopecia with heterogeneous severity and distribution. Previous studies found conflicting results about the epidemiology of AA. We performed a systematic review of all published cohort and cross-sectional studies that analyzed AA, and excluded other types of alopecia.MEDLINE, EMBASE, LILACS, Scopus, Cochrane library and GREAT were searched. The pooled prevalence of AA, alopecia totalis (AT), ophiasis (AO), and universalis (AU) were determined and stratified by population source, study region, study year and age.
