BMI and baseline D-Ser plasma concentration as predictors of KET

	Model	Variables	R²	R² Change	F (for Change)	df	p (for Change)
A	1	BMI	0.353	0.353	10.35	1,19	0.005
	2	BMI, baseline D-serine	0.626	0.274	13.18	1,18	0.002
B	1	Baseline D-serine	0.596	0.596	28.01	1,19	<.001
	2	Baseline D-serine, BMI	0.626	0.030	1.47	1,18	0.242

A: BMI is a significant predictor of outcome (model 1). In addition, D-serinemakes a significant addition to the variance explained by BMI (model 2). B: D-serine is a significant predictor (model 1), but there is no additional variance explained by BMI (model 2)
