|Trait||Included factors||n||AUC||Brier score||R2|
|Overweight||SNPs + nongenetic||2,679||0.64||0.23||0.106|
|Obesity||SNPs + nongenetic||1,968||0.69*||0.17||0.168|
To perform the ROC analysis, information regarding all 20 validated BMI/obesity variants must be available when SNPs are the included factors. Information regarding all conventional obesity risk factors must be available when nongenetic factors are the included factors, and information regarding all 20 variants plus all conventional obesity risk factors must be available when SNPs and nongenetic factors are the included factors. This explains the decreasing number of included individuals with increased number of included factors. R2, partial R2 for explained variance.
