Chromosomal areas with gain those are significantly different between betel quid chewers (BQC) and non betel quid chewers (NBQC) breast cancer patients.

Frequency of chromosomal regions with significantly different (P<0.05; see Materials and methods for the statistical test) alterations between TBC and NTBC tumors are depicted. Most significant regions, based on the criteria of P<0.05 and a relatively low FDR value, are indicated in bold. FDR  =  false discovery rate.
