CSF1R and lung cancer: In a Cox regression analysis (Table 2), high expression levels of CSF1R were associated with high lung cancer-specific mortality in both univariable (HR = 2.90, 95% CI = 1.41−6.11, p = 0.0041) and multivariable analyses (HR = 2.66, 95% CI = 1.28−5.66, p = 0.0088) in never-smoking patients; however, such associations were not observed in univariable (p = 0.73) or multivariable analyses (p = 0.54) in ever-smoking patients.
