Description
Shanshan Li, Yanwen Liu, and Chenggang Liu map research on overlapping lung and sleep disorders in a 2026 analysis. Chronic lung disease plus sleep apnea forms a recognized overlap syndrome. Its literature has grown without a systematic map. Bibliometrics can chart who publishes what, where.
Three databases were mined for a quarter century of work. The main set held over twelve hundred publications. Annual growth averaged above twenty percent. Output jumped noticeably after 2017. Three countries led publication counts by volume. International co-authorship stayed surprisingly rare at six percent. Core themes included night oxygen drops and heart outcomes. Flare-ups and airway pressure therapy anchored the knowledge base. Topic modeling found ten latent themes in the corpus. Two themes trend upward sharply in recent years. The map guides newcomers to hotspots and gaps. Collaboration building is an implied recommendation.
