After the greater initial decrease ( @-@ weeks ) in glycated haemoglobin ( HbA@c ) with glipizide , the @-@-week HbA@c coefficient of failure ( CoF ) was lower with dapagliflozin ( @ % / year ) than with glipizide ( @ % / year ) , resulting in significant dapagliflozin versus glipizide differences of -@ % / year ( @ % CI -@ , -@ ; p = @ ) for CoF and -@ % ( -@ mmol/mol ) -LSB- @ % CI -@ ( -@ ) , -@ ( -@ ) ; p = @ -RSB- for @-week HbA@c .
