Advantages and Disadvantages of the Lewis Score, CECDSI, and CDACE on the Basis of Our Study Results

	Lewis Score	CECDAI	CDACE
Advantage	• Automatic calculation by software. • Easy recognition of stenosis (with high scores).²¹ • With validation.¹⁹	• Reflects the degree of inflammation in the entire small intestine compared to LS.²¹ • With validation.²⁰	• It shows extent of inflammation. • Provide information on presence and extent of stenosis. • Correlates with existing scores.
Disadvantage	• Only one third of the most inflamed small intestine areas are reflected in the score. • Are high scores due to inflammation or stenosis?²¹	• Manual calculation. • No clue to presence or absence of stenosis from the score values.²¹	• Manual calculation. • Without validation (this manuscript only).
