Despite extensive research on IH, leadership classification in publications remains underexplored. This study introduces a novel bibliometric approach by integrating Kano diagrams and absolute advantage coefficients (AACs) to classify leaders within IH research.A total of 2817 articles and reviews published from 2015 to 2024 were retrieved from the Web of Science Core Collection. The analysis consisted of 2 parts: summarizing the overall publication AAC and classifying leaders across the top 10 metadata entities. An online R-based bibliometric module was used, incorporating the follower-leading clustering algorithm to visualize Kano-based leadership classifications. Leadership was categorized as super (AAC ≥ 0.8), quasi-super (≥0.7), strong (≥0.6), moderate (≥0.5), and weak (<0.5). The top 20 entities for each metadata category were visualized.The United States led publications, followed by China, with a weak advantage (AAC = 0.23). Other leading entities included Shanghai Jiao Tong University (China, strong, 0.60), the Dermatology department (moderate, 0.54), author Xiaoxi Lin (China, weak, 0.45), the Pediatric Dermatology journal (quasi-super, 0.70), the Pediatrics research area (weak, 0.49), and the keyword "CHILDREN" (weak, 0.44). Notably, Dr Xiaoxi Lin also achieved a super leadership rating (AAC = 0.88) based on individual publication profile analysis.The Kano integrated with AAC approach effectively identifies and classifies research leadership in publications of IH, offering a novel lens to evaluate dominance and influence across metadata entities in bibliometric studies.enKano diagramabsolute advantage coefficientbibliometric analysisinfantile hemangiomaleadership classification[SDGs]SDG3text::journal::journal article10.1097/MD.000000000004490541054051
