Correlations of radiomics features with PFS outcomes and clinical characteristics and intercorrelations of radiomics features. (A-H) Boxplots of log-transformed radiomics features stratified for patients with or without an event (progression and/or death) on the 3-years PFS. (I) Spearman rank correlation coefficient plot of all radiomics features. Asterisks indicate significance values (∗P < .05; ∗∗P < .01; ∗∗∗P < .001). (J-N) Boxplots of log-transformed radiomics features stratified for Ann Arbor stage. (O-S) Boxplots of log-transformed radiomics features stratified for the presence of B symptoms at baseline. D_max, the largest distance between 2 lesions in mm; DSUV_peakBulk, difference of SUVpeak between the largest lesion and the lesion with the lowest SUVpeak in g/mL; Dvol, the difference in volume between the largest and the smallest lesion in mL; NumberLesions, number of lesions; TLR_SUVmean, tumor-to-liver ratio of mean SUV corrected for the liver SUV_mean; TLR_SUVpeak, ratio of SUV_peak corrected for the liver SUV_mean.
