N, total number of cases; FC, fold change.

a

Threshold cycle (CT) is the unit of measurement in qRT-PCR to measure relative gene expression. Difference in CT (ΔΔ CT) = Tumor change in Ct minus paired non-tumor change in CT.

b

Fold change calculated from ΔΔCt, where fold change = 2-(median ΔΔ CT). Median fold change values are represented.

c

Q1 and Q3 for inter-quartile range of fold change values.
