SAA1 and adenocarcinoma: There were statistically significant differences in CRP concentration between female and male adenocarcinoma patients (p = 0.0411; meanF = 4.42 mg/L, meanM = 23.93 mg/L; raw mean difference [D] = 19.51 mg/L), MMP-2 concentration in SqCC patients (p = 0.0065; meanF = 114.10 ng/mL, meanM = 151.53 ng/mL; D = 37.43 ng/mL), and SAA1 concentration in other NSCLCs (p = 0.0068; meanF = 13.51 μg/mL, meanM = 298.14 μg/mL; D = 284.63 μg/mL).
