All participants were categorised into quartiles according to the blood concentrations of the fatty acid profiles and metabolic enzymes. Continuous variables were presented as means ± standard deviations. The difference among the quartiles was assessed using analysis of variance. The chi-square test was used to test the significance among the categorical data.
To compare the different fatty acids in predicting the CVD risk, we used the following strategies: Multivariable Cox proportional hazard models were used to estimate the HR and their respective 95% CI (see Supplementary Materials for the details of Models 1–3). All analyses were performed using SAS version 9.3 (SAS Institute, Cary, NC) and R version 3.3.0. Two-tailed P-values of <0.05 were considered to indicate statistical significance.
