I may be reading it wrong, but the participants were told to only test once daily.
Well, what use is that? Absolutely none. It is meaningless, and clearly the researchers had no idea how to use meters to the best advantage.
The medical profession in charge of Type 2 diabetic patients have no clue about testing out food, before and after, and using the results to discover what they can or can't eat. When I explained to my lovely nurse how I did this she was amazed. She is a senior nurse, specialises in diabetes, and presents our local X-Pert courses. No-one had ever told her about this way of controlling diabetes. It had never been part of her training - and she keeps up with her training.
From what I read on here, those lucky enough to be prescribed strips are told to test maybe once a day after main meal, but aren't told to test before it, and aren't told what levels they should expect to see. To me this is a complete waste of strips, and gives no-one the opportunity to learn.
