Methods: Five hundred one diabetes patients with experience in self-monitoringof BG were randomized to use three of five different BGM devices (FreeStyle Lite® [Abbott Diabetes Care Inc., Alameda, CA], FreeStyle Freedom Lite [Abbott Diabetes Care], OneTouch® UltraEasy® [LifeScan Inc., Milpitas, CA], Accu-Chek® Aviva [ Roche Diagnostics, Mannheim, Germany], and Contour® [Bayer Vital GmbH, Leverkusen, Germany]) in a daily routine setting. All devices and strips were purchased from local regular distribution sources (pharmacies, four strip lots per device). The patients performed the finger prick and the glucose measurement on their own. In parallel, a healthcare professional performed the glucose assessment with the reference method (YSI 2300...
