Figure 2From: MDM2 SNP309 is associated with high grade node positive breast tumours and is in linkage disequilibrium with a novel MDM2 intron 1 polymorphism SNP309 genotype distribution in relation to menopausal status and tumour estrogen receptor status. A – ER positive defined as ER Score ≥ 4. ER negative defined as ER Score <4. B – Highly ER positive breast tumours defined as ER Score ≥ 12. Values expressed as a percentage for each group. The mean age of breast cancer diagnosis in relation to menopausal status and tumour estrogen receptor status. C – ER positive defined as ER Score ≥ 4. ER negative defined as ER Score <4. D – Highly ER positive breast tumours defined as ER Score ≥ 12. Error bars ± 95%CI.Back to article page
