*Betty's absolute values of HbA1c, BMI, and INS/d from 2015 to the last check-up. The Animas insulin pump was implemented in 2007. The two peaks on the blue line (INS/d) in the years 2015 and 2019 correlate to Betty's pregnancies when the insulin dosage nearly doubled and lowered HbA1c, indicating better metabolic control. Pregnancy is symbolized by yellow stars. The last two check-ups show high INS/d (110 U/d) and increased body mass with no sustainable effect on HbA1c (red box).*
