Table 2 Univariate Cox regression for cancer-specific survival in the extended clear cell renal cell carcinoma cohort 2 (n = 108)

From: Clinical utility of the S3-score for molecular prediction of outcome in non-metastatic and metastatic clear cell renal cell carcinoma

Univariate analyses Variable Level No. of cases HR (95% CI) P value c-index
(Log-rank test)
All patients S315-score high 87 1 (Ref.) 5.15 × 10–5 0.69
   low 21 4.96 (2.10–11.72)   
M0 S315-score high 77 1 (Ref.) 1.62 × 10–2 0.68
   low 15 4.37 (1.17–16.29)   
M1 S315-score high 9 1 (Ref.) 2.31 × 10–3 0.71
   low 6 9.32 (1.75–49.58)   
  1. CI confidence interval, HR hazard ratio, Ref. reference level
  2. S315-scores were determined based on gene expression data measured by RT-PCR; tumors with metastasis status MX were disregarded
