At 6 months , mean glycated haemoglobin had decreased by 11 % ( SD 12 ; 12 mmol/mol , SD 13 ) in the pump treatment group and 04 % ( SD 11 ; 4 mmol/mol , SD 12 ) in the multiple daily injection group , resulting in a between-group treatment difference of -07 % ( 95 % CI -09 to -04 ; -8 mmol/mol , 95 % CI -10 to -4 , p < 00001 ) .
