Distribution of various clinical parameters among patients with chronic pancreatitis groped according to the results of mutational screening for the SPINK1 and PRSS1 genes

SPINK1PRSS1Mutation negative
Results from the PRSS1 and SPINK1 gene analysis were used to divide the cohort of chronic pancreatitis: SPINK1, patients who had at least one mutated SPINK1 allele (N34S and/or P55S); PRSS1, patients who had the N29I or R122H PRSSI mutation; Mutation negative, patients who did not have one of the mentioned mutations (wild-type).
Percentages refer to the proportion of patients within each given group.
Type A pain represents recurrent pain attacks while type B pain indicates unrelenting continuous pain.
