The factors were the length of stay (coefficient = 0.054, 95% CI: 0.049-0.060, p < 0.001), lymphoma (coefficient = 0.067, 95% CI: 0.012-0.121, p = 0.017), severe sepsis (coefficient = 0.081, 95% CI: 0.020-0.142, p = 0.009), 18–40 years age group (coefficient = 0.082, 95% CI: 0.019-0.144, p = 0.011), treatment with therapeutic GCSF (coefficient = 0.101, 95% CI: 0.041-0.161, p = 0.001), and staying on a private ward (coefficient = 0.408, 95% CI: 0.359-0.457, p < 0.001). The gene discussed is CSF3; the disease is lymphoma.
