Table 5 Multivariate (logistic regression) analysis in the diagnosis of Fuhrman grades 3–4 ccRCC

From: Tumor grade of clear cell renal cell carcinoma assessed by contrast-enhanced computed tomography

  Odds ratio 95% CI P-value
Size* 1.2 1.1 – 1.4 0.00083
Infiltrative 4.9 1.6 – 15.4 0.0059
Calcification 0.9 0.3 – 2.5 0.78
Lobulated 4.9 0.9 – 27.7 0.069
Non-enhancing area ≥60% 1.7 0.7 – 3.9 0.20
  1. Note. CI = confidence interval. The data were analyzed in total 214 ccRCC cases.
  2. *Tumor size and infiltrative growth are significantly associated with grades 3–4 RCC.
