Supplemental Material for: Vertical Vessel Proportion as a Predictor of Vascular-Targeted Photodynamic Therapy Efficacy in Port-wine Stains: A Prospective Observational Study

This dataset contains the supplemental materials for the brief report titled "Vertical Vessel Proportion as a Predictor of Vascular-Targeted Photodynamic Therapy Efficacy in Port-wine Stains: A Prospective Observational Study", published in the Journal of the American Academy of Dermatology (JAAD). The files provided include: Representative clinical photographs and OCTA en face images of responders and non-responders (Fig S1-S2). Algorithmic schematics illustrating the projection of 3D vascular orientations onto a 2D plane (Fig S3). Comparative ROC curve analysis of VVP against conventional structural metrics (Fig S4). Detailed baseline demographics and multivariable regression analysis results (Tables S1-S2). Detailed MATLAB pseudocode outlining the custom image-processing pipeline for VVP quantification (Text S1). These materials provide comprehensive methodological details and support the clinical findings regarding the predictive value of vertical vessel orientation in PWS treatment outcomes.本数据集包含发表于《美国皮肤病学会杂志》（JAAD）的题为《垂直血管比例作为葡萄酒色斑（Port-wine Stains, PWS）血管靶向光动力治疗（Vascular-Targeted Photodynamic Therapy）疗效预测因子：一项前瞻性观察研究》的简报的补充材料。 所提供的文件包括： 1. 应答者与无应答者的代表性临床照片及光学相干断层扫描血管造影（Optical Coherence Tomography Angiography, OCTA）正面观图像（图S1~S2）； 2. 展示3D血管取向投影至2D平面的算法示意图（图S3）； 3. 垂直血管比例（Vertical Vessel Proportion, VVP）与常规结构指标的对比受试者工作特征（Receiver Operating Characteristic, ROC）曲线分析结果（图S4）； 4. 详细的基线人口统计学资料及多变量回归分析结果（表S1~S2）； 5. 用于VVP量化的自定义图像处理流程的详细MATLAB伪代码（文本S1）。 这些材料提供了全面的方法学细节，支撑了关于垂直血管取向对葡萄酒色斑治疗结局预测价值的临床研究发现。
