Abbreviations: IQR, interquartile range; LOCRC, late-onset colorectal cancer; EOCRC, early-onset colorectal cancer; CRC, colorectal cancer. Continuous data are analyzed with unpaired two-sided T- or Mann–Whitney tests; dichotomous and categorical data are analyzed with Pearson’s χ2-test and Fisher’s exact test.
