I would love to see these studies talk about variability, maybe measured as standard deviation, particularly in the third trimester, in addition to A1C. CGM is a tool to report and so facilitate management to minimize variability in ways finger stick can not. I would love a study that looks at the question - can women be coached and supported to manage glycemic variability with a CGM in ways that reduce third term hypers and hypos that has an impact on birth weights? Is this variability management more predictive of healthy birth weight than A1C?
That seems to me to be closer to the right questions or is it just me?
ps. It was really hard for me not to make jokes here. Sadly I would think that if Secher is used to deny CGM insurance coverage as an option to help coach women in pregnancy it would be a case of Murphy's law not Murphy's study.
