Peer-reviewed publications about rheumatoid arthritis have been on the rise for the last 30 years.
As the body of literature around rheumatoid arthritis has grown, the most details have emerged about its pathogenesis, diagnosis, and treatment. A recent study published in Medicine highlights the top 100 articles focused on rheumatoid arthritis that have revealed the most data.
Investigators analyzed studies, published from 1985 to Dec. 31, 2017, in Web of Science, a database with articles from nearly 9,000 journals. The site also provides citation index searching, a function that helps evaluate academic importance. Two reviewers independently screened the abstracts and full texts to identify the top 100 most cited rheumatoid arthritis articles.
“By analyzing contents of clinical studies in the past three decades, we found that the diagnosis and treatment of early rheumatoid arthritis was gradually gaining importance in the rheumatoid field,” investigators said.
These articles show a progression of how rheumatoid arthritis has been diagnosed. There is no single test or criteria that confirms the diagnosis, but these publications show updates in the diagnostic criteria every few years with the goal of earlier disease identification, the researchers said.
Overall, the top 100 articles were published in 24 journals. The most common was Arthritis & Rheumatism (n=33), totaling 44,765 citations. An additional 37 percent of articles were published in other high-impact journals. As expected, studies published in those high-impact journals were cited most frequently.
The top 100 (T100) articles were divided into several categories: clinical study, review, meta-analysis, clinical guidelines, and basic science. Clinical studies accounted for most of the articles (n=55), focusing mainly on identifying the effectiveness or safety of a drug therapy. Randomized controlled trials were the most common (n=32), followed by prospective-cohort studies, case-controlled studies, case series, retrospective-cohort studies, and cross-sectional studies.
The content of these articles also fell into several categories, including classification criteria, evaluation of drug therapy, disease activity evaluation, pathogenesis, risk factor, and description of epidemiology. Studies on the evaluation of drug therapy appeared the most (n=48), and they provided an analysis of drug treatment strategy effectiveness and the risks of other diseases post-treatment.
Articles focused on clinical guidelines revealed rheumatoid arthritis classification criteria, management recommendations with different drug types, advice on evaluating disease activity pre- and post-treatment, and cardiovascular risk management. These studies, which provided guidance for proper diagnosis and treatment, also explored other risk factors, such as genetic factors (IL2RA, CCL21, and AFF3).
The review did have some limitations, investigators said. The analysis was limited to articles pulled from Web of Science, and no studies published in non-English languages were included. In addition, self-citations were not taken into consideration.
Although this article examines the growth of rheumatoid arthritis publications over the past 30 years, researchers said, it likely does not cite all of the most influential articles.
“The latest publications may not be included in the T100 articles, as the more recent studies have not had sufficient time to accumulate the number of citations,” they said.
