Consensus (Parkes) Error Grid Analysis
The Consensus Error Grid Analysis (CEG) is another standard for quantifying the accuracy of CGM systems. CEG is
similar to the Clarke EGA in that it assigns the dierences (errors) between the CGM system values and reference
values to one of 5 “clinical risk” regions. But the CEG diers from the Clarke EGA in that the risk regions are
continuous (A through E), whereas with the Clarke EGA they are not continuous (e.g., A is next to D).
CEG percentages were calculated for the total number of CGM readings.
