aSNP, single-nucleotide polymorphism; MUC4, mucin 4 gene. Allelic frequencies were determined by Fisher's exact test using 2 × 2 contingency tables. Genotype frequencies were determined by Fisher's exact test using 2 × 3 contingency tables. bMild stage, patients at clinical stage1 or stage 2; cSevere stage, patients at clinical stage 3 or stage 4; dP < 0.05 was considered statistically significant.
