Supplemental Material for: Personalized UVA1 Phototherapy Strategies for Steroid-Refractory Hand-Foot Eczema: A Prospective Study

This supplemental file provides additional figures and a table supporting the main findings of the study.

Contents:

Supplemental Figure 1: Representative cases of hand eczema patients undergoing UVA1 phototherapy in both low and high-frequency treatment cohorts. The figure illustrates the progression of skin lesions in patients with fissured and hyperkeratotic conditions, as well as those with dyshidrotic or recurrent vesicular eczema, at various treatment timepoints.
Supplemental Figure 2: UVA1 phototherapy outcomes in hand-foot eczema patients with different lesion types across low and high-frequency regimens after 15 sessions. The figure shows the proportions of patients achieving HECSI-75 and HECSI-90 response rates.
Supplemental Figure 3: Additional UVA1 phototherapy outcomes, including changes in HF-Peak Pruritus NRS and HF-Peak Pain NRS scores, recurrence times, and the correlation between initial palmar epidermal thickness and the number of treatments needed to reach IGA 0/1.
Supplemental Table 1: Baseline demographics and clinical characteristics of the study participants, comparing the low-frequency and high-frequency treatment groups.
These supplemental materials provide detailed clinical data and visual documentation to enhance the interpretation of the study results.
