A new analysis of the 50 most-cited research articles on pediatric respiratory infections reveals that the United States, China, and Canada produced nearly half of the influential work. The review, covering articles published between 1978 and 2021, found that over half of these papers came out in the 2010s, highlighting a recent surge in research attention.
The studies mostly looked at clinical outcomes like pneumonia and bronchiolitis, as well as viral causes such as RSV and SARS-CoV-2, and antimicrobial stewardship. Two-thirds were cohort studies, while only 12% were randomized trials. The most-cited article had 384 citations, but most had fewer, showing a skewed distribution.
However, the findings come with important caveats. The analysis relied heavily on observational studies from high-income countries, and there were few randomized trials, systematic reviews, or multicenter collaborations. Research led by low- and middle-income countries was also scarce. This means the picture of pediatric respiratory infections may be incomplete, especially for regions where these infections are most common.
For readers, this review offers a snapshot of where research attention has been focused, but it does not provide new clinical guidance. It underscores the need for more diverse, high-quality studies to better understand and treat childhood respiratory infections worldwide.
