Table 1 Conformity of particular variables to normal distribution. Apparent diffusion coefficient, the standard deviation in the region of interest. Microsoft Corporation, Microsoft Word 2013 (version 15.0.5389.1000).
| Variable | Kolmogorov-Smirnov test | Shapiro-Wilk test | Variable distribution |
|---|---|---|---|
| ADC mean value | d=0.07, p>0.2 | W=0.98, p=0.21 | Normal |
| ADC SD-in-ROI | d=0.11, p | W=0.95, p=0.0006 | Not normal |
| ADC minimum value | d=0.07, p>0.2 | W=0.97, p=0.017 | Not normal |
| ADC maximum value | d=0.09, p>0.2 | W=0.96, p=0.008 | Not normal |
| ADC – apparent diffusion coefficient; SD-in-ROI – standard deviation in the region of interest. | |||
