Fig. 6From: The detection of specific hypermethylated WIF1 and NPY genes in circulating DNA by crystal digital PCR™ is a powerful new tool for colorectal cancer diagnosis and screeningCRCs ctDNA compared to control group in liquid biopsies. Comparison of NPY (A) and WIF1 (B) hypermethylation in liquid biopsies of patients with a CRC compared to control group by Mann Whitney test. The red line represents the specific threshold of positivity: ≥1 positive droplet for NPY and ≥ 5 positive droplets for WIF1Back to article page
