Tumor size ≥ 3 cm	0.229 (0.060-0.872)	0.031
Lower esophagus	0.433 (0.127-1.476)	0.181
Overestimation
Lower esophagus	3.393 (0.785-14.664)	0.102
Underestimation

Circumferential spread ≥ 3/4	2.328 (0.542-9.995)	0.256

¹All variables were included in the multivariate analysis, including those variables that were and were not significantly associated with accuracy, overestimation, and underestimation in univariate analyses.
