Possible program errors were observed when contouring inferior margin of mass for one H/L case having a tumor with a cystic component.

Three AA cases also do not have these parameters generated and are not included in this table.

PDAC, pancreatic ductal adenocarcinoma; AA, African American; H/L, Hispanic/Latinx; NHW, non-Hispanic White; cm, centimeters.

Bold font indicates a P value < 0.05.
