^aSamples positive to NF-κB/p65 (Staining score ≥3). Intensity of staining reported as score and num of crosses. 0 (−), no-staining; 1 (+), weak; 2 (++), moderate; and 3 (+++), strong. Extent of staining reported as score and percentage because of its variability. CRC, colorectal cancer; NF-κB, nuclear factor-κB.
