Difference between postoperative levels of B2M and PPIA stratified for the patient group. cfDNA levels depicted as boxplot showing median, upper and lower quartiles. Whiskers extend into a max of 1.5 times the interquartile range. Observations outside this are displayed as outliers. Wilcoxon rank-sum test was used for analyzing the difference between groups, Kruskal–Wallis test for difference across groups. A shows the difference in postoperative levels of B2M stratified for patient groups. B shows the difference in postoperative levels of PPIA stratified for patient groups. cfDNA: cell-free DNA, PPIA: Peptidyl-Prolyl cis–trans Isomerase A, B2M: Beta-2-microglobulin
