Table 4 Multivariate Cox hazard ratio models for the impact of low cholesterol on cancer-specific and overall survival after surgical treatment of metastatic renal cell carcinoma

From: Preoperative cholesterol level as a new independent predictive factor of survival in patients with metastatic renal cell carcinoma treated with cyto-reductive nephrectomy

  Cancer-specific survival Overall survival
HR 95% CI of HR p-value HR 95% CI of HR p-value
Entire cohorts 2.162 1.221–3.829 0.008 2.013 1.206–3.361 0.007
Subgroups according to the tumor histology
 Clear cell histology 2.312 1.274–4.193 0.006 2.204 1.279–3.799 0.004
 Other histology 0.767 0.076–7.771 0.822 0.285 0.043–1.879 0.192
Subgroups according to the Heng’s model
 Favorable risk 1.556 0.487–4.967 0.455 1.767 0.602–5.185 0.300
 Intermediate 1.809 0.907–3.611 0.093 1.583 0.851–2.947 0.147
 Poor 1.538 0.339–6.972 0.577 1.735 0.406–7.416 0.457
