Univariate analysis was performed to identify the baseline characteristics affecting the treatment response, including clinical type of pemphigus, age, body weight, disease duration, corticosteroid dose, PDAI score, serum anti‐Dsg autoantibody levels, and presence or absence of adjuvant immunosuppressants; however, none of the aforementioned factors were associated with treatment response (Table S1). The gene discussed is DSG1; the disease is pemphigus.
