Cost effectiveness analysis of different approaches of screening for familial hypercholesterolaemia

Occasionally, an error only comes to light a year or more after publication, as is the case with this paper by Dalya Marks and colleagues, which was published in June last year (BMJ 2002;324: 1303-6). The error occurred only in the full length version of the paper (on bmj.com); the abridged version was correct. Somehow, in the production process, we managed to publish one table twice (as table 3 and table 4). The table is correct as table 4, but table 3 should have shown the “comparison of number needed to be invited to screening and screening costs (ages 16-54 years) for different strategies using clinical and genetic confirmation of the diagnosis” (in other words, the table that was called table 2 in the abridged version). The correct table 3 now appears with the full version (bmj.com/cgi/content/full/324/7349/1303/DC1).
