For various reasons, journals may convert from subscription-based to open-access (OA) publishing models, commonly referred to as flipping. In 2022, the Acta Obstetricia et Gynecologica Scandinavica flipped to OA. We performed a bibliometric analysis of authorship patterns in this journal during and after the flipping period. A total of 898 research articles were included. In the period after flipping to OA, there were more publications by authors in various countries, including from China (7.2% vs. 3.3%, P = 0.001). Accordingly, the flip to OA in a leading obstetrics and gynaecology journal seemed to impact the authorship locale.
