The risk score for each CRC patient in GSE17536 was assessed using the following equation: Risk score = (−1.74 × AARS2 expression) + (0.36 × ATF4 expression) + (2.08 × CARS2 expression) + (2.98 × CRP expression) + (0.40 × CYBA expression) + (−0.61 × FOXO3 expression) + (0.68 × GPX1 expression) + (0.06 × IL1B expression) + (0.52 × MAPK8 expression) + (0.47 × MRPL44 expression) + (0.09 × MTFMT expression) + (1.43 × NOS1 expression) + (1.04 × OSGIN2 expression) + (0.14 × SOD2 expression). The gene discussed is ATF4; the disease is colorectal carcinoma.
