Scientists at Queen Mary, University of London, have announced a new machine-learning-based method for predicting the biological therapy, or biologic, most likely to successfully relieve symptoms for an individual with rheumatoid arthritis. The scientists say that their system successfully predicted the optimal biologic for 79–85% of patients on its first try in validation tests. Over the last 20 years, biologics have revolutionized the treatment of rheumatoid arthritis (RA) due to their
