Multivariate Dosage Prediction of Changes in HbA1c and LDL Levels

	R²	Significant predictor variables (direction)	P value	Other variables
Change in HbA1c
Dosage factors	0.48	Face time (−)	.005	Baseline HbA1c (−)
Dosage factors	0.48	Frequency (+)	.004	Risk Score (+)
Dosage clusters	0.50	Active disease treatment (−)	.02	Baseline HbA1c (−)
Dosage clusters	0.50	Brief intense (−)	.01	Risk Score (+)
Change in LDL
Dosage factors	0.49	None		Baseline LDL (−)
				Risk Score (−)
Dosage clusters	0.49	Brief intense (−)	.04	Baseline LDL (−)
Dosage clusters	0.49	Active coordination (−)	.07	Risk Score (−)

HbA1c = Hemoglobin A1c; LDL = low density lipoprotein
