In a Cox regression analysis, high expression levels of CSF1R were associated with high lung cancer-specific mortality in both univariable (HR = 1.61, 95% CI = 1.02−2.52; p = 0.043) and multivariable analyses (HR = 1.32, 95% CI = 1.00−2.49, p = 0.048) (Table 2). Here, CSF1R is linked to lung cancer.
