Performance Summary for External Validation on Block D for the Global Model Estimated on Blocks A, B, and C.

	Avg r2	MAD (mg/dL)	MARD (%)	CEG A+B (A) (%)
Initial baseline adjustment	0.50	109	107	80.7 (30.9)
+ Initial baseline adjustment at “stable” glucose	0.49	56.3	49.9	83.5 (33.0)
+ Novelty detection	0.51	52.2	46.4	84.2 (34.6)
+ Output filtering	0.50	42.1	35.4	86.9 (39.1)

Table entries show the performance improvement due to each processing routine. “Stable” glucose means SMBG rate of change within [–2, +2] mg/dL/min.
