CEACAM6, carcinoembryonic antigen-related cell-adhesion molecule 6; LGALS4, lectin galactoside-binding soluble 4; TSPAN8, tetraspanin 8; COL1A2, collagen type I alpha 2 chain; ΔCq, mean quantification cycles after normalisation on reference gene; SD, standard deviation. FITN, faecal immunochemical test negative; F, females, M, males; 50–59, people aged between 50 and 59 years old; 60–70, people aged between 60 and 70 years old. * indicates a significant difference between males and females (p value < 0.05); ‡ indicates a significant difference between older males and older females (p value < 0.05).
