Kovatchev et al. (1) reported anomalous performance results of three continuous glucose monitoring (CGM) sensors during a hypoglycemia clamp study. The authors stated that “all three CGM sensors experienced periods of transient loss of sensitivity, particularly during hypoglycemia, identified as sensor readings holding steady at a very low glucose value (e.g., 2.1 mmol/l) ….”
This study did not evaluate CGM systems per their intended …
