Accuracy of continuous nocturnal glucose monitoring after 48 and 72 hours in type 2 diabetes patients on combined oral and insulin therapy

Continuous glucose monitoring system during physical exercise in adolescents with type 1 diabetes

“…MARD for different glucose ranges showed no significant difference during the first 48 h. This is in agreement with Nyback‐Nakell et al. (28) who regarded the accuracy as acceptable at 48 h (correlation = 0.80) after which time it deteriorated.…”

Is the Response of Continuous Glucose Monitors to Physiological Changes in Blood Glucose Levels Affected by Sensor Life?

“…As mentioned earlier, this is because none of these studies matched testing conditions between consecutive days, examined lag time, and addressed CGM performance in response to rapid changes in blood glucose levels, [5][6][7][8][9][10][11][12][13][14][15] and all of these studies overlooked the potential confounding effect of the decrease in blood glucose variability with CGM time of wear. 21 In contrast, these limitations were overcome in this study by exposing the unit on consecutive days to a reproducible pattern of change in blood glucose levels.…”

“…Although most but not all 5 studies suggest that sensor performance remains relatively stable over 3, 6-9 5, 10-12 6, 13 7,14 or 10 15 days, many of these studies did not support their findings with any statistical analyses, 5,7,8,10,13,14 and several important accuracy issues were not addressed. For instance, it remains to be established whether several days of wear affect sensor accuracy under conditions of rapid changes in blood glucose levels.…”
