    In the October 2006 issue of Evidence-Based Medicine, calcuation errors were detected in the table of the abstract for the article by Prince et al.1 The numbers needed to treat (NNTs) for compliant patients were incorrect.

    The correct NNTs for calcium v placebo in compliant patients are these:

    Any fracture NNT 21 (95% CI 13 to 235)

    Appendicular fracture NNT 22 (CI 13 to 225)

    Upper limb fracture NNT 34 (CI 24 to 238)
