 Janus med sex and gender is a knowledge database designed to provide evidence-based information on sex and gender aspects in drug therapy. It has collected and evaluated data on 400 drugs, with 20% showing clinically relevant sex differences, 22% lacking any sex-related data, and 52% not showing any significant differences between males and females. Additionally, many studies do not include sex-specific analysis, making it difficult to accurately assess the impact of sex on drug responses.
