AIP and autoimmune pancreatitis: This relationship continued to show significance when AIP was divided into quartiles; EAT-v progressively increased per quartile of AIP (Quartile 1: 39.4 [IQR 27.1–56.4] cm3; Quartile 2: 52.3 [IQR 38.3–69.0] cm3; Quartile 3: 53.7 [37.7–85.4] cm3; Quartile 4: 63.5 [IQR 46.2–83.9] cm3; p = 0.029; see Fig. 4), with significant pairwise differences between Quartile 1 and each subsequent quartile (all p < 0.05; see Fig. 4).
