The forecasted share of corresponding/leading authors in scientific publications in cardiology and cardiovascular medicine in Brazil shows a gradual decline from 93.08% in 2024 to 91.9% in 2028. This reflects a continuing trend, possibly influenced by broader international collaboration and changing authorship norms. In 2023, the actual value was slightly above the 2024 forecast, aligning with the historical data trend. Year-on-year analysis indicates a small but consistent decrease, signaling a compound annual growth rate (CAGR) negatively impacting retention of domestic lead authorship.
Future trends to watch include the impact of increasing international joint research ventures, shifts in funding patterns, and policy changes affecting research focus and publication practices in Brazil. Monitoring these factors will be crucial to understanding the evolving landscape in scientific research authorship within the region.
