RESUMO
Identifying citation classics is a valuable metric of research performance. Ireland has a distinguished history of medical research, although Ireland's top-cited articles are unknown. The SCOPUS database identified all medical and surgical articles published by journals in the Republic of Ireland or Northern Ireland. The 100 top-cited articles were analysed. The most cited article received 240 citations. There is an observed trend of increasing number of authors over time (p<0.05). General medicine and public health are the most common topics. The majority of works originate from Irish institutions. Collaborative research and non-Irish research are poorly represented among the citation classics. The Irish medical literature contains multiple highly cited and influential articles.
