Study Workflow for Analyzing Alopecia Areata (AA). Two datasets were used: GSE68801 (122 samples: 60 AA, 62 NC) as the primary dataset for analysis and GSE80342 (15 samples: 12 AA, 3 NC) for external validation. The workflow involved analyzing differentially expressed genes (DEGs) and ferroptosis-related DEGs (FRDEGs) in these datasets. AA, alopecia areata patients; NC, normal controls; DEGs, differentially expressed genes; FRDEGs, ferroptosis-related differentially expressed genes.
