*Clark's absolute values of HbA1c, BM, and INS/d show relatively constant values of HbA1c and INS/d over 9 years of time, while his body mass changed within a range of 88 kg and 98 kg. Treatment with an insulin pump was initiated in 2009. Followed by the insulin pump Paradigm Veo 554 implemented in April 2013, MiniMed 640G in April 2017, and MiniMed 780G in January 2022. Using CGM could potentially improve HbA1c concentration with a lower number of insulin units needed.*
