Re: “Does practice make perfect? The effect of coaching and retesting on selection tests used for admission to an Australian medical school”, by Barbara Griffin, David W Harding, Ian G Wilson and Neville D Yeomans, in the 1 September 2008 issue of the Journal (Med J Aust 2008; 189: 270-273). In the Results section, under “Prevalence of coaching”, the words “were more likely to be male (57.6% v 44.4%; χ2 = 4.88; P = 0.03)” should read “were more likely to be male (57.6% v 42.4%; χ2 = 4.88; P = 0.03)”.
