Table 4 Concordance rate for grading between EUS-FNA and surgical specimens.

EUS-TA diagnosis	Total (n)		Surgical diagnosis (n)		Concordance rate	Kappa coefficient
EUS-TA diagnosis	Total (n)		G1	G2	% (95% CI)	κ	P
Statistically significant P values are indicated in bold. Gray backgrounds indicate lesions where grading did not match. 95% CI, 95% confidence interval; κ, Cohen's kappa coefficient; P, P value for kappa coefficient.
