In 2023, the share of corresponding/leading author in scientific publications in pulmonary and respiratory medicine in the US stood at a certain baseline. Between 2024 and 2028, a gradual decline is forecasted: from 93.65% in 2024 to 93.39% in 2028. Year-on-year percentage variations indicate a consistently slight decrease, reflecting a very modest downward trend. The five-year compound annual growth rate (CAGR) confirms an annual average decline, albeit very slight.

Future trends to watch for include:

Impact of collaboration initiatives on author shares in research publications.
Possible shifts due to changes in publication practices or policies emphasizing diverse authorship.
The effect of novel research tools and collaboration platforms on corresponding author roles.
