Restricted cubic spline models for the relationship between dietary CoQ10 intake and new-onset hypertension stratified by average dietary fat intake and baseline drinking status. (A) Total, (B) plant-derived, (C) animal-derived dietary CoQ10 stratified by average dietary fat intake. (D) Total, (E) plant-derived, (F) animal-derived dietary CoQ10 stratified by baseline drinking status. Adjusted, if not stratified, for at baseline age (continuous), sex (male/female), BMI (continuous), education (middle school or below/high school/college or above), smoking status (yes/no), drinking status (yes/no), physical activity (continuous), residence (urban/rural), marital status (yes/no), and cumulative average intake of energy (continuous), vegetables (continuous), and fruits (continuous). The likelihood ratio test was used to calculate the P interaction.
