Frequency of Nocturnal Hypoglycemia in the Juvenile Diabetes Research Foundation Continuous Glucose Monitoring Randomized Control Trial^a

	Hypoglycemic threshold
Binary outcomes	≥70 mg/dl	≥60 mg/dl	≥50 mg/dl
	% of nights
Single value hypoglycemic	25.4%	14.8%	7.6%
2 consecutive values hypoglycemic	23.3%	13.2%	6.7%
20 consecutive minutesa hypoglycemic	18.4%	9.7%	4.5%
60 consecutive minutes hypoglycemic	9.7%	4.6%	2.0%

^aContinuous glucose monitoring data were evaluated from 10:00 pm to 6:00 am during the first six months of the study in 231 subjects in the CGM treatment group (age 8–72 years, baseline HbA1c 4.7–10.6%). Analysis was restricted to the 25,473 nights with at least 6 h of CGM data, ranging from 3 to 182 per subject.
