Metagenomic predictions of qualitative and quantitative traits.

Accuracy of prediction with confidence intervals for human and bovine metagenomic predictions. Phenotypes were predicted from metagenomic profiles using BLUP, performed in ASReml. To evaluate the accuracy of metagenomic predictions the predicted phenotype was correlated with the measured (real) phenotype. IBD and BMI data is from [8].

95% confidence interval of the Pearson’s correlation coefficient r based on 10,000 bootstraps.

Ref.Pop. = Reference population.

Val.Pop = Validation population.

Spain-c = Control samples from Spain (no IBD).

bovFT-t/bovGMC-t = Animals on the treatment diet only.

bovFT-c/bovGMC-c = Animals on the control diet only.

N = total number of samples used.

CV = Cross Validation.

2 Populations = Validation on a second independent population.

Phenotypes used were IBD = 0, nonIBD = 1.
