  • Data are mean (SD) unless otherwise indicated. For reasons for discontinuing CGM, n = 64 for 18–25 age-group, n = 58 for 26–34 age-group, n = 75 for 35–50 age-group, n = 48 for >50 age-group, n = 149 for women, and n = 86 for men. For reasons for discontinuing insulin pump, n = 24 for 18–25 age-group, n = 21 for 26–34 age-group, n = 18 for 35–50 age-group, n = 9 for >50 age-group, n = 51 for women, and n = 18 for men. For HbA1c, n = 93 for 18–25 age-group, n = 100 for 26–34 age-group, n = 139 for 35–50 age-group, n = 120 for >50 age-group, n = 271 for women, and n = 171 for men.
