Why the study?
Antibodies against phosphorylcholine are implicated as protective markers in cardiovascular disease, but previous studies have mostly focused on IgM rather than IgG subclasses.
Are low levels of IgG1 anti-PC associated with an increased risk of incident cardiovascular disease in 60-year-olds?

Low IgG1 anti-PC levels may flag higher CVD risk in 60-year-olds; leaves open whether measurement or immunization strategies merit prospective trials.
Are low levels of IgG1 anti-PC associated with an increased risk of incident cardiovascular disease in 60-year-olds?
Low levels of IgG1 anti-PC are strongly associated with an increased risk of incident cardiovascular disease and stroke, particularly in men, suggesting its potential as a protective biomarker.
