Reliability of symptom-blood glucose relationships among insulin-dependent adult diabetics.

Symptoms and blood glucose levels were recorded by 23 insulin-dependent diabetics during three separate intervals. Each interval spanned 7-10 days, involving 40 symptom-blood glucose recordings. Each symptom's ratings were correlated with their respective blood glucose recording to yield a separate symptom-blood glucose correlation for each interval. These separate symptom-blood glucose relationships were themselves correlated across the three intervals to assess the temporal stability of the symptom-blood glucose relationships. Reliability was found to be variable. Possible explanations for this variability are discussed.
