Patients without Pancreatic mass (n = 110c)

  1. PDAC pancreatic ductal adenocarcinoma, CP chronic
  2. aIncluded the 13 patients whose imaging were performed at other hospitals
  3. bIncluding the data of 25 patients with PDAC, the data of 13 patients were excluded, including those with pancreatic pseudocyst (n = 5), these with IPMN (n = 2), and these whose imaging examinations were performed at other hospitals (n = 6)
  4. cMissing values and only five patients with PDAC, which are not enough for establishing a regression model
