We discuss methods of developing consensus in measuring improvement in myositis. We consider selecting candidate variables, reliability and validity, percentage improvement/worsening rules, rules based on CART and logistic regression. We discuss criteria for determining an acceptable rule that include both numerical measures and physician acceptance.
