Results of Univariate and Multivariable Analysis for the Differentiation of Tumors Grouped by Gleason Score (GS)

Variable Univariate Analysis Multivariable Analysis
OR (95% CI) p OR (95% CI) p

 Tumor volume 1.41 (0.91–2.17) 0.123
 Median ADC value 0.69 (0.56–0.86) 0.001
 Median Ktrans value 1.02 (0.98–1.07) 0.300
Tumors with a GS of 3 + 3 or 3 + 4 vs those with a GS of 4 + 3 or higher
 Tumor volume 1.30 (1.00–1.68) 0.052
 Median ADC value 0.71 (0.58–0.87) 0.001 0.63 (0.49–0.82) 0.001
 Median Ktrans value 1.06 (1.02–1.09) < 0.001 1.07 (1.04–1.10) < 0.001
Tumors with a GS of 3 + 3, 3 + 4, or 4 + 3 vs those with a GS of 4 + 4 or higher
 Tumor volume 1.12 (1.04–1.20) 0.002
 Median ADC value 0.66 (0.49–0.88) 0.004 0.46 (0.28–0.76) 0.002
 Median Ktrans value 1.07 (1.04–1.10) < 0.001 1.11 (1.07–1.17) < 0.001

Note—ADC = apparent diffusion coefficient, Ktrans = volume transfer constant.
