¹Both endoscopic ultrasound-elastography (EUS-E) and contrast-enhanced harmonic EUS (CH-EUS) positive for malignancy.

²At least one technique (EUE-E or CH-EUS) positive for malignancy.

EUS: Endoscopic ultrasound; EUS-E: EUS-elastography; CH-EUS: Contrast-enhanced harmonic EUS; EUS-FNA: EUS-guided fine needle aspiration.
