Sintesi	The Crohn's Disease Activity Index (CDAI) is a comprehensive, weighted index for assessing disease activity in Crohn's disease. Developed in 1976 by Best and colleagues for the National Cooperative Crohn's Disease Study, the CDAI integrates eight clinical and laboratory variables into a single score ranging from <150 (remission) to >450 (severe activity). Although more complex than symptom-based tools, the CDAI captures the multidimensional nature of Crohn's disease and remains the reference standard for severe disease assessment.	The Mayo Score is a validated tool for assessing disease activity in ulcerative colitis, integrating clinical symptoms and endoscopic findings. Introduced by Schroeder and colleagues in 1987, it has become the reference standard for UC activity assessment in clinical trials and practice. The score combines stool frequency, rectal bleeding, overall physician global assessment, and endoscopic subscore into a single 0–12 scale.
