Note—Values in parentheses are 95% CI. The odds ratio expresses the odds of patients having clear cell renal cell carcinoma relative to patients with the parameter value 1 unit lower. For apparent diffusion coefficient (ADC), the odds ratio was estimated for every increment of 0.0001, and for downslope for every increment of 10.
