From: LRIG1 gene copy number analysis by ddPCR and correlations to clinical factors in breast cancer
Frequency distributions of LRIG1 and ERBB2 copy number ratios and ER levels and relationships between LRIG1 copy number ratios and breast cancer subtypes among 423 breast cancer cases. a Frequency distributions of LRIG1/CYP1B1 ratios determined by ddPCR. b Frequency distributions of ERBB2/CYP1B1 ratios determined by ddPCR (c) Frequency distributions of ER levels retrieved from clinical records. d Box plots of LRIG1/CYP1B1 ratios for each tumor subtype
