A recent study analyzed preprints from medRxiv and found a significant increase in the use of em-dashes following the widespread adoption of large language models (LLMs). The prevalence of em-dashes in discussion sections rose from 4.23% before November 2022 to 11.58% afterward, indicating a shift in writing style. While the study cannot definitively prove causality, the gradual acceleration of this trend and its consistency across various analyses suggest a notable change in scientific literature composition coinciding with the early 2020s.
