Association of Helicobacter pylori and Chlamydia pneumoniae infections with coronary heart disease and cardiovascular risk factors

An editorial error occurred in this paper by Dr P Patel and colleagues (16 September, pp 711-4). “Factor VIIa” was spelt out incorrectly as “factor VII antigen.” It should have been spelt out as “activated factor VII.” This is important because factor VII antigen is the inactive form and its concentration in plasma (measured as % of normal) is not a particularly good marker of clotting activation.
