Evaluating clinical accuracy of continuous glucose monitoring devices: other methods.

With more and more continuous glucose monitoring devices entering the market, the importance of adequate accuracy assessment grows. This review discusses pros and cons of Regression Analysis and Correlation Coefficient, Relative Difference measures, Bland Altman plot, ISO criteria, combined curve fitting, and epidemiological analyses, the latter including sensitivity, specificity and positive predictive value for hypoglycaemia. Finally, recommendations for much needed head-to-head studies are given.
