Pancreatic volume change using three dimensional-computed tomography volumetry and its relationships with diabetes on long-term follow-up in autoimmune pancreatitis

Figure 2 Scatter plot and regression curve. A: Relationship between relative volume change of pancreas and follow-up period in all 33 patients with type-1 autoimmune pancreatitis. Mean relative volume change reduced exponentially and rapidly during the first 25 months of follow-up and then more slowly; B: Diffuse (D-) and mass-forming (M-) types resembled the overall regression curve. The regression curve was lower for patients with D-type compared with M-type autoimmune pancreatitis; C: Relative pancreatic volume change decreased gradually and slightly over time during long-term follow-up in 10 control subjects with normal pancreas.
