title: Cyclic changes in insulin needs of an unstable diabetic.
abstract: The fluctuating insulin requirements of an unstable diabetic over an 8-year period have been subjected to spectral analysis. There is evidence of cyclic changes of several different period lengths in addition to red noise. The periodicities indicate that social causes play no major role but suggest that a weathermediated effect may exist.
