Continuous Glucose Monitoring System Accuracy During Compression Challenge (n = 15)

Condition	No. of paired CGM system-YSI reference readings	Percent within 15/15% reference	Percent within 20/20% reference	Percent within 30/30% reference	Percent within 40/40% reference	MARD (%) [95% CI]
Compression	274	86.1	92.3	96.0	99.6	9.3 (5.3–12.9)
No compression	16,379	85.7	93.4	98.1	99.4	8.7 (8.1–9.3)

In-clinic accuracy is assessed compared with venous YSI reference measurement. The effect of compression on accuracy was evaluated by instructing participants with bilaterally placed sensors to lie on one side for 30 min. Results compared with the noncompressed side are reported. The percentage of system readings within ±15 mg/dL or 15% of YSI reference values (15/15%), ±20 mg/dL or 20% of YSI reference values (20/20%), ±30 mg/dL or 30% of YSI reference values (30/30%), or ±40 mg/dL or 40% of YSI reference values (40/40%) are reported.
