- Higher composite dietary antioxidant index (CDAI) is associated with lower odds of self-reported history of treated pelvic inflammatory disease (PID) among women.
- The association was evaluated using survey-weighted multivariable logistic regression and restricted cubic spline analysis, showing an inverse linear trend.
- Odds ratios for PID across CDAI quartiles (vs. lowest quartile) were: Q2 OR=0.682, Q3 OR=0.524, Q4 OR=0.666.
- Among CDAI components, vitamin E intake independently showed an inverse association with PID odds.
- SHAP value interpretation identified vitamin A, vitamin C, and carotenoids as the top predictive contributors within CDAI.
- Subgroup analysis revealed a significant interaction effect of age on the CDAI-PID association.
