In a randomised , prospective , open @ factorial design , the once-weekly performance of four-point glucose profiles ( SMBG + ; n = @ patients ) was compared with no SMBG ( SMBG - ; n = @ ) , and the measuring and transmitting of HbA@c results to the study centres ( HbA ( @c ) + ; n = @ , of these @ SMBG - and @ SMBG + ) was compared with HbA@c measurement without disclosure of results ( HbA ( @c ) - ; n = @ , of these @ SMBG - and @ SMBG + ) .
