(the authors are German so I suspect the patient recruitment was in that
area)
They started with patients with an A1c around 7 and on oral meds only.
Then
they compared patients testing once a week with those testing ~4 times a
week with the tests before dinner and one test before lunch. Both groups
maintained an A1c around 7.
I think those of us who have come to m.h.d. will want better A1c's and use
SMBG to gain a different set of data and make some lifestyle adjustments.
