CRYAB and gastric cancer: The risk score for each stomach cancer patient was calculated according to the following formula: risk score = (0.1865 × expression of CD24) + (0.1524 × expression of CRYAB) + (0.1090 × expression of MMP11) + (0.0911 × expression of MUC4) + (0.1548 × expression of PRKAA2) + (0.1262 × expression of SERPINE1) + (-0.2236 × expression of SKP2) + (-0.1465 × expression of TP53) (Table S11).
