The sensitivity, specificity, positive predictive value, and negative predictive value of total EREFS ≥ 2 for the diagnosis of EoE were 100%, 56.2%, 56.6%, and 100%; for the caterpillar sign, those values were 83.3%, 98.1%, 96.2%, and 91.2%, respectively. Interobserver agreement for identification of the caterpillar sign was substantial (κ = 0.80) CONCLUSIONS: The caterpillar sign could be a novel reliable indicator for endoscopic diagnosis of EoE.
