Distensibility plateau (DP). Baseline and follow-up DP plots for the same two patients as in Figure 1 ((a) treated with topical steroid, positive patient-reported outcome; (b) treated with dietary therapy, negative patient-reported outcome) are displayed. Points represent the narrowest luminal diameter by nadir pressure at each incremental distension volume. The DP was calculated from the polynomial trendlines.
