A1C reduction was no different between the two groups. Subjects in the CG group had increased hypoglycemia AUC and number of events during blinded CGM use; however, there was no increase in hypoglycemia AUC or number of events in the SG group. Subjects with greater sensor utilization showed a greater improvement in A1C levels.
No statistically significant differences in accuracy were evident using the Clarke EGA criteria (pooled results of Zone A and B), though the more strict 20% accuracy criteria (Zone A results only) found the Flash and Contour to have significantly greater accuracy compared to the Advantage, Compact Plus, and the Logic. Using the 10% accuracy criteria found the Flash to have significantly greater accuracy than each of the other four meters. All five meters demonstrated similar precision.
The Abbott Optium was significantly more accurate than the other meter systems, whereas the HDI True Track was significantly less accurate and less precise compared to the other meter systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
