Model 1 Model 2 Model 3
One year 0.661 ± 0.013 0.751 ± 0.010 0.833 ± 0.008
Two years 0.663 ± 0.012 0.748 ± 0.010 0.830 ± 0.007

Data presented as C-Indexed ± standard error.

Predictors included the final models:

Model 1 (pancreatic morphologic features only): atrophy, calcification, focal pancreatic duct stricture with distal (upstream) dilatation, and intra-ductal calculi (duct stone).

Model 2 (pancreatic morphologic features + patient demographics/clinical features): atrophy, calcification, focal pancreatic duct stricture with distal (upstream) dilatation, sex, race/ethnicity and change in weight.

Model 3 (pancreatic morphologic features + patient demographics/clinical features + lab measures): atrophy, calcification, race/ethnicity, change in weight, fasting glucose, hemoglobin A1c and alkaline phosphatase.
