Box-and-whisker plot of changes in TAR > 180 mg/dL (A), TAR > 250 mg/dL (B), average IG concentration mg/dL (C) and GMI % (D). Data represented as plots are median, first quartile (Q1 or 25th percentile) and third quartile (Q3 or 75th percentile), min and max, mean (as a cross) and all individual points for changes calculated from DG4 parameter at M3 or M6 or M12 − FSL1 parameters expressed as percentage points except for average IG concentration which is in mg/dL. Values indicated are means ± SD or median [Q1;Q3]. Data are from 21 T1D followed-up patients. Abbreviations: DG4, Dexcom platinum G4; FSL1, FreeStyle Libre version 1; GMI, glucose management indicator; IG, interstitial glucose; TAR, time-above-range.
