Fig. 3: Comparison of image features between TFE3-RCC and ccRCC.

For each feature, the fold change is defined as the ratio of the median feature values between ccRCC and TFE3-RCC. 52 image features that show significant differences between TFE3-RCC and ccRCC are identified using the two-sided Mann–Whitney U test. Multiple comparison correction is performed using false discovery rate procedure at 5% level.
