Relationship of pancreatic duodenal homeobox-1 (PDX1) expression with mucins (MUC5AC, MUC6) and trefoil factors (TFF2, TFF3) in intestinal metaplasia (IM) and spasmolytic polypeptide expressing metaplasia (SPEM)

Types of metaplasia/PDX1	MUC5AC (+)	MUC6 (+)	TFF2 (+)	TFF3 (+)
IM (n = 61)
PDX1 (+) (n = 60)	60	2	29	60
PDX1 (–) (n = 1)	1	0	0	1
Value of p*	0.000a	1.000	0.08	0.000a
SPEM (n = 36)
PDX1 (+) (n = 32)	14	32	32	9
PDX1 (–) (n = 4)	0	4	4	1
Value of p*	0.007b	0.000a	0.000a	0.04b
