Well done 👏@DrCMcMaster @victor_yang1 on this great work - using machine learning to pick apart GCA from its mimics. Predicting mimics improves prediction, especially in the quagmire of biopsy-negative GCA (also excellent memes in this Twitter thread) #ACR21 ABST1417 @RheumNow https://t.co/cS3fMLwem4
