Mediation effects of CRP on associations of total, dinner and Δ DAC with all-cause mortality

Abbreviations: HRs, hazard ratio; CIs, confidence intervals; CRP, C-reactive protein; DAC, dietary total antioxidant capacity; TE, total effect; NIE, natural indirect effect; NDE, natural direct effect, HEI-2015, Healthy Eating Index 2015; BMI, body mass index; CVD, cardiovascular disease. HR (95%CI) was estimated by weighted Cox regression analyses. Model was adjusted for, age, sex and race, education, family income, dietary energy intake, alcohol consumption per day, smoking status, physical activity, BMI, diabetes, hypertension, CVD, cancer, hyperlipidaemia, adherence to HEI-2015 score, and dietary supplement use. Models for dinner DAC were further adjusted for breakfast DAC and lunch DAC.
