Differences in tumor tissue bile acids between left-sided colon cancers (LCCs) and right-sided colon cancers (RCCs) from patients ≥ 55 years old. Stages I–III combined (LCC n = 99, RCC n = 98). Data represent median with interquartile range. Nonparametric Wilcoxon Mann–Whitney U test, p values adjusted for false discovery rates (FDR) (Benjamini–Hochberg). *p < 0.05, **p < 0.01, ***p < 0.001, ns.  not significant; CA cholic acid, CDCA chenodeoxycholic acid, TCA taurocholic acid, TCDCA taurochenodeoxycholic acid, GCA glycocholic acid, GCDCA glycochenodeoxycholic acid, DCA deoxycholic acid, LCA lithocholic acid, UDCA ursodeoxycholic acid, TDCA taurodeoxycholic acid, TLCA taurolithocholic acid, GDCA glycodeoxycholic acid, GLCA glycolithocholic acid, GUDCA glycoursodeoxycholic acid, DCA deoxycholic acid, TDCA taurodeoxycholic acid, GDCA glycodeoxycholic acid
