Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Identify different trajectories of insulin sensitivity throughout the menstrual cycle	Insulin sensitivity factor based on data from continuous glucose measurements, insulin administration throughout the menstrual cycle	6 months
Secondary	Total daily Insulin dose throughout the menstrual cycle	Data from the insulin administration devices	6 months
Secondary	Coefficient of glucose variability throughout the menstrual cycle	Data from continuous glucose monitoring systems	6 months
Secondary	Estimated insulin sensitivity throughout the menstrual cycle	Modeling insulin sensitivity using data from the insulin administering devices, nutrition data, and CGM data.	6 months
Secondary	Glycaemic profile (mean glucose, time in range, time above range, time below range, coefficient of variability) throughout the menstrual cycle	Data from continuous glucose monitoring systems	6 months
Secondary	Correlations between insulin sensitivity trajectories and confounders	Data on carbohydrate estimations, activity, and insulin application profiles	6 months
