Bar plots illustrating the percentage of radiomics features that were statistically significant at the p ≤ 0.05 level broken down by texture family. Overall, only 4.74% of all variables reached statistical significance in univariate analyses; however, analyses did reveal increased representation of LTE-derived features. GLSZM, gray-level size zone matrix; LTE, Laws Texture Energy; NGTDM, neighboring gray tone difference matrix; GLRLM, gray-level run length matrix; FFT, fast Fourier transform; GLDM, gray-level dependence matrix; DCT, discrete cosine transform; GLCM, gray-level co-occurrence matrix.
