A neglected infection in literature: Childhood musculoskeletal tuberculosis – A bibliometric analysis of the most influential papers

Pediatric tuberculosis (TB) is known to have a wide range of presentations, and if left untreated, primary TB may lead to bone and joint involvement. The literature on this topic is very scarce, and no comprehensive systematic review or meta-analysis of the current knowledge is available to date. The aim of this study is to identify and analyze the literature with highest impact based on citation rate analysis. All databases of the Thomson and Reuters "Web of Knowledge" were used to conduct our search of the 100 most cited articles on this topic published between 1950 and 2014. The included articles were analyzed in terms of citation rate, age, study type, area of research, level of evidence (LOE), and more. All 100 articles were published between 1967 and 2011 in 51 different journals. The average citation rate was 74.26, all articles were on average 23.1 years, and most studies were originated from India (n = 22), followed by the USA (n = 21). The majority of publications were review articles (42%), described clinical course (n = 48), and assigned an LOE IV (44%). TB infection is a high burden disease in low-income countries but widely studied in a fi rst world setup. This research gap between the geographic distribution of disease burden and origin of publications could initiate possibilities for high-burden countries to share their opinion. Their experience is of a high level of importance and relevance which furthermore is necessary to create a more accurate picture of pediatric musculoskeletal TB burden in literature.
