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.
