Predictive Factors for Long-Term High Responders to Upadacitinib Treatment in Patients with Atopic Dermatitis

Upadacitinib, a Janus kinase 1 inhibitor, is an effective medicine for moderate-to-severe atopic dermatitis (AD). Identifying long-term responders to upadacitinib is crucial for optimal treatment strategies in real-world clinical practice.
