From: Perioperative changes in cell-free DNA for patients undergoing surgery for colon cancer
Change in cfDNA in alleles per mL vs. group and operation type. 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 depicted as outliers. Wilcoxon rank-sum test was used for analyzing the difference between groups, Kruskal–Wallis test for difference across groups. A shows the relationship between changes in PPIA levels and patient group. B shows the relationship between changes in B2M levels and the patient group. C shows the relationship between changes in PPIA levels and operation procedure. D shows the relationship between changes in B2M levels and operation procedure. cfDNA: cell-free DNA, PPIA: Peptidyl-Prolyl cis–trans Isomerase A, B2M: Beta-2-microglobulin
