Cut points for activity states according to various indexes (Panel A) and components of response criteria (Panel B). Yes, required; no, not required; yes/no, in the ACR criteria, 3 of the variables marked "yes/no" are required (0 or 1 laboratory measure). TJC, tender joint count; SJC, swollen joint count; VAS, visual analogue scale; HAQ, health assessment questionnaire.
