Confirmation of the reference impedance ratios used for assessment of breast cancer-related lymphedema by bioelectrical impedance spectroscopy.

The choice of the mean + 3 SD as the criterion value may be questioned as being too conservative compared to a criterion of the mean + 2 SD more common in diagnostic testing. This threshold value was originally proposed by Cornish et al. but without supporting explanation for its choice. Its use in the present study was based upon this historical precedent.
