In addition, a significant trend of increasing risk of breast cancer was observed when p16 INK4a mRNA expression increased ( p < 0.001).
In addition, a significant trend of increasing risk of breast cancer was observed when p16 INK4a mRNA expression increased ( p < 0.001).
A marginally significant association was further observed in the validation stage with 47 cases and 48 controls using pre-diagnostic samples (OR = 1.28; 95%CI: 0.98, 2.97; p = 0.053).
A similar trend was also observed for education, with lower education having higher p16 INK4a mRNA expression, but the difference did not reach statistical significance.
