Nonlinear Dose–response analysis on the association of PD score and PLL score with the risk of CRC (A/D: all CRC; B/E: proximal colon cancer; C/F: distal CRC). For PD score, hazard ratio was adjusted for age, sex, race, education levels, family history of colorectal cancer, history of colon comorbidity, history of diverticulitis or diverticulosis, history of colorectal polyp, history of diabetes, history of aspirin use, total energy intake, BMI at baseline, smoking status, and physical activity level. For PLL score, hazard ratio was adjusted for age, sex, race, education levels, family history of colorectal cancer, history of colon comorbidity, history of diverticulitis or diverticulosis, history of colorectal polyp, history of diabetes, history of aspirin use, total energy intake
