An error occurred in the title and abstract of this paper by S F T M de Bruijn and others (21 February, pp 589-92). The title should have been: Case-control study of risk of cerebral sinus thrombosis in oral contraceptive users and in carriers of hereditary prothrombotic conditions. The objective in the abstract was wrong in the same respect.
