The researchers looked at approximately 3m pull requests submitted on GitHub, and found that code written by women was approved at a higher rate (78.6%) than code written by men (74.6%).

… “Women’s acceptance rates dominate over men’s for every programming language in the top 10, to various degrees,” the researchers found.

… they made the disturbing discovery: women’s work was more likely to be accepted than men’s, unless “their gender is identifiable”, in which case the acceptance rate was worse than men’s.
