從政策辯論到實證證據：FDA規範前後非處方助聽器研究之概念驗證性文獻計量與大型語言模型輔助摘要層內容分析

// From policy debate to empirical evidence: a proof-of-concept bibliometric and LLM-assisted abstract-level content analysis of OTC hearing aid research before and after FDA regulation

本研究透過文獻計量與大型語言模型輔助摘要標註，分析FDA OTC聽力助聽器類別實施前後的研究趨勢｜比較106篇文章，發現研究焦點顯著減少對高齡族群的關注，且從評論性研究轉向實證研究｜結果指出研究重心在立法階段即開始轉變，方法有效快速勾勒研究全景，但揭示服務不足族群與地理覆蓋的缺口。

// This study analyzed temporal trends in over-the-counter hearing aid research before and after the FDA's OTC category implementation using bibliometrics and large language model (LLM)-assisted abstract annotation. Researchers compared 106 articles from pre- and post-implementation periods, finding a significant reduction in focus on older adults and a shift from commentary to empirical studies. The analysis suggests research reorientation began during legislative phases, not just after market entry. The method shows promise for quickly mapping research landscapes but highlights gaps in underserved populations and geographic coverage.
