In 2023, the share of corresponding/leading authors in scientific publications in Pulmonary and Respiratory Medicine in Brazil was slightly higher than that forecasted for 2024 at 92.47%. The data from 2024 to 2028 indicates a gradual annual decline, reflecting a consistent decrease of about 0.32% per annum, revealing a subtle yet steady downward trend.

Future trends to watch for include:

Impact of international collaborations which might further affect the proportion of local leading authors.
Shifts in research funding and focus areas which could influence author dynamics.
Changes in academic policies and incentives that may alter trends in authorship.
