Distribution of PI-RADs classification using MRI and tissue stiffness using USWE in low/intermediate risk and high risk cancer prostate cancers based on Gleason score
| Measurements | Low/intermediate risk# GS group (n = 97) | % | High risk^ GS group (n = 99) | % | Pearson Chi-square | Degree of freedom | P value |

*PI-RADS classification 3 means intermediate probability of clinically significant prostate cancer, 4 means high probability and 5 means very high probability of clinically significant prostate cancer; # Gleason score 3 + 3 and 3 + 4 were considered as low/intermediate risk cancer
