MDR Analyses

Sample	Best Model	Cross Validation	Prediction Error	p value
Whole	2 (Age, Gender)	10	33.1 %	< 0.001
Non-obese group	3 (Age, ADRB2-16, UCP3)	10	32.5 %	< 0.001
Obese group	-	-	-	n. s.

Sample: sample of the analysis. Best Model: number of factors and which factors best predict the disease status in sample. Cross Validation: value of the consistency of the model across the 10 repeated test. Prediction Error: percent of subjects incorrectly classified following the proposed model. p value: significant level calculated through a 1000-fold permutation method.
