Data of 223 continuous glucose monitoring (CGM) users in the Juvenile Diabetes Research Foundation CGM randomized controlled trial¹² who had at least 25 nights, each with at least 6 h of data (n=25,370 nights).

^{^a}

Defined as follows: A/a, single CGM value ≤60 mg/dL; B/b, single CGM value ≤70 mg/dL; C/c, two consecutive values ≤60 mg/dL; D/d, two consecutive CGM values ≤70 mg/dL; E/e, time CGM below 60 mg/dL; F/f, time CGM below 70 mg/dL; G/g, area under the curve (≤70 mg/dL); and H/h, Low Blood Glucose Index.
