Multivariable logistic regression analyses of the three levels of DII scores for PC risk by sex. DII was adjusted for sex, age, BMI, smoking, and energy intake. DII was divided into three ranges, low, medium, and high DII, from the lowest to the highest. ORs and 95% CIs were evaluated to determine the relationship between the three levels of DII scores and PC risk using a multivariable logistic regression analysis for PCs and HCs. (A) ORs and 95% CIs among the three levels of DII; (B) ORs and 95% CIs among the three levels of DII for males; (C) ORs and 95% CIs among the three levels of DII for females. * p < 0.05. The p-values for trends were computed by treating the values as continuous variables, evaluating the continuous scale, and allocating median values to each quantile. Abbreviations: OR, odds ratio; CI, confidence interval; Ref, reference value; DII, dietary inflammatory index; PC, pancreatic cancer; HC, healthy control.
