Figure 2 Box plots of patient-assessed EoE severity distribution by endoscopic/histologic activity. The box contains the 25th–75th percentiles of values, the horizontal line in the middle of the box represents the median. Eos, eosinophils.

Figure 3 (A) The correlation plot between the EEsAI PRO score and the PatGA in the validation group. (B) The Bland–Altman plot for the agreement between the EEsAI PRO score and the PatGA in the validation group. The grey box indicates the 95% limits of agreement.
