We chose the year 2000 as a human baseline to establish a threshold for AI involvement. We also selected the years 2015 and 2020 to observe changes in AI probability scores. Considering the release of ChatGPT in November 2022, we included abstracts from 2023 to 2025 to determine the increase in AI usage. We classified articles into native English-speaking, non-native English-speaking, and mixed groups to determine authorship nativity based on institutional affiliations. We used Originality.AI to report AI probability scores. We evaluated differences across years and nativity groups using the Kruskal-Wallis and post hoc tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Across the 6 time periods, 1885 abstracts were analyzed. AI probability scores from the year 2000 (n = 124; mean, 1.68%) were significantly lower than all subsequent years (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001 for all pairwise comparisons). Scores remained stable between 2015 (n = 348; mean, 9.39%) and 2020 (n = 383; mean, 8.91%;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2265 .999). However, scores began a rapid and significant increase starting in 2023 (n = 345; mean 15.48%) and continued to rise through 2025 (n = 323; mean, 30.6%;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001) compared with all previous years. The percentage of abstracts exceeding the threshold increased consistently throughout the years, from 4% in the 2000 baseline to 62.5% in 2025. When nativity groups were compared within the Generative AI Era, no statistically significant differences in AI probability scores were observed in 2023 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .364), 2024 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .053), or 2025 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .454).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our study demonstrated that the prevalence of AI-like linguistic patterns in AJSM abstracts has increased since the release of ChatGPT.
