  1. aVariable number of samples is reported due to clinical sample limitations. bLow methylation is referred to as methylation similar to the methylation level observed in the 1% methylation standard. cMethylation-positive samples are referred to as samples displaying a HRM profile characteristic for cases. dMethylation level similar to the one observed in the 1% to 10% methylation standard.
