Furthermore, a significant trend was observed among individuals with impaired fasting glucose (IFG; -0.16, 95% CI -0.30 to -0.01, P = 0.03), while no significant changes were found in those with impaired glucose tolerance (IGT; P = 0.40).These findings underscore the importance of dietary copper intake in reducing cardiovascular mortality among hypertensive patients across various demographic and clinical subgroups, with notable variations in effects based on ethnicity, education level, and diabetes status(see table 4 ).
