FIG. 1. — (a) The MARD of FGM (FreeStyle Libre) in relation to glucose levels measured by HemoCue as an exponentiated quadratic function of glucose levels measured by HemoCue. Figure shows each single measurement as well as the predicted MARD with 95% CI. (b) The MAD of FGM (FreeStyle Libre) in relation to glucose levels measured by HemoCue as an exponentiated quadratic function of glucose levels measured by HemoCue. Figure shows each single measurement as well as the predicted MAD with 95% CI. (c) Scatter plot of measurements of glucose levels by FGM (FreeStyle Libre) versus HemoCue. The red line represents for one–one relation. The figure shows a greater concentration of values below the red line, indicating lower mean glucose levels by FGM than mean glucose levels obtained by HemoCue. CI, confidence interval; FGM, flash glucose monitoring; MAD, mean absolute difference; MARD, mean absolute relative difference.
