  1. Factors and costs are expressed as means per patient per day (24 hours). 195% confidence interval based on 1,000 stratified bootstrap samples; 2assuming a lifetime of two years; 3assuming a manufacturers’ sensor lifetime of two and a half days; 4calibration strip CGM; 5includes syringes, nonsterile gloves, gauzes, alcohol, cap (used for blood sampling) and testing strip POC; 6costs for a single point-of-care glucose measurement. CGM: continuous glucose monitoring, POC: point-of-care.
