Evolutionary Trends and Research Focal Points on Port Wine Stains: A Scientometric and Meta-Analysis.

Background: Despite numerous studies over the past two decades, clinical treatment for port wine stains (PWS) has shown limited progress. Analyzing evolutionary trends and research focal points can illuminate current deficiencies and guide future investigations. We aim to conduct a scientometric analysis and meta-analysis to uncover the historical trajectory, research hotspots, and future directions of PWS.
