Three errors crept into this news article by Caroline White (10 January, p 67). In the sixth paragraph we inadvertently referred to datasets in two papers being the same, instead of two sets of patients being the same. In the following paragraph, we referred to the number of digits remembered by patients as part of a memory test. The numbers given in the submitted paper refer to scores, however, so cannot be reliably converted into digits. The relevant sentence should therefore read: “One was the implausibly high score relating to the number of digits remembered by the participants.” Lastly, Dr Jack Strawbridge is director of faculty relations (not labour relations) at Memorial University.
