Participants at greater risk of cardiovascular disease had significantly greater mean ( SE ) reductions in diastolic blood pressure ( -@ @ mm Hg compared with -@ @ mm Hg ) , cholesterol ( -@ @ mg/dL compared with +@ @ mg/dL ) , and triglycerides ( -@ @ mg/dL compared with +@ @ mg/dL ) ( n = @ , @ , and @ , respectively ; P < @ ) than did those at lower risk , who did not have significantly different cholesterol or triglyceride concentrations .
