I see a common problem with reports like this one: they do not take the time in range (TIR) metric into account. Especially closed loop systems reduce both hypers and hypos, which is clearly a big improvement. But because the hba1c has the characteristic of an average value, reductions in both high and low blood sugars cancel each other out, and the hba1c remains largely unchanged. Admittedly, this is not relevant if the hba1c is something like 11%, because that is far too high no matter what. But someone with 7% can experience such an improvement in glycemic stability and still remain at 7% for example.
