VL-Ref (all)
VL-Ref/CL-Scout+	238	−0.22 (−0.35 to −0.09)	−2.17 (−2.39 to −1.95)	1.73 (1.51 to 1.95)
VL-Ref/CL-Nova	238	0.46 (0.36 to 0.56)	−1.08 (−1.25 to −0.91)	2.00 (1.83 to 2.18)
VL-Ref/VL-Scout+	240	0.22 (0.17 to 0.26)	−0.46 (−0.53 to −0.39)	0.90 (0.82 to 0.98)
VL-Ref/VL-Nova	240	0.83 (0.77 to 0.88)	−0.01 (−0.10 to 0.084)	1.66 (1.57 to 1.76)

The point estimate of the level of agreement (LOA) being within ±0.4 mmol/L from the point of the bias considered as clinically acceptable; and the point estimate of the LOA within ±0.2 mmol/L from the point of the bias considered as good agreement.
