This letter by Polasek and Kolcic (BMJ 2005;331:1204, 19 Nov) contains a couple of errors. Firstly, the second author's name is given the wrong way round—it should be Ivana Kolcic, rather than the more unusual Kolcic Ivana. Secondly, the authors provided the wrong results from their analysis of final year medical students from Zagreb's medical school. The last sentence of the second paragraph should read: “The logistic regression results indicate that better ranked students (odds ratio 2.60, 95% confidence interval 1.16 to 5.82), younger medical students (odds ratio 0.83, 0.73 to 0.95), and those interested in scientific work (odds ratio 3.10, 1.10 to 8.84) considered emigrating from Croatia.”
