[RESULTS] Both algorithms had significant and equivalent reductions in HbA1c from baseline ( study A : Q3D -0.96 % [ -10.49 mmol/mol ] , Q1D -1.00 % [ -10.93 mmol/mol ] , Q3D-Q1D 0.04 % [ 0.44 mmol/mol ] [ 95 % CI -0.15 to 0.22 ( -1.64 to 2.40 ) ] ; study B : Q3D -0.92 % [ -10.06 mmol/mol ] , Q1D -0.98 % [ -10.71 mmol/mol ] , Q3D-Q1D 0.06 % [ 0.66 mmol/mol ] [ 95 % CI -0.12 to 0.24 ( -1.31 to 2.62 ) ] ) .
