Table 2. Shows clinical variables of 318 cases of pancreatic cystic lesions.
| Clinical variable | Pancreatic cystic lesions (n = 318) | Case Distribution: M = mucinous PCN NM = non-mucinous PCL |
|---|---|---|

The univariate analysis is performed between different characteristics in mucinous (M) and non-mucinous (NM) cases primarily classified by the proposed algorithm. Statistically significant differences are shown in bold.
