Validation of the model: prediction scores for children with other causes of respiratory distress. To determine some diagnostic accuracy, the metabolomic model of healthy children vs. RSV was presented blinded metabolomic data from children with respiratory distress from non-RSV infections. Illustrated are the PLS-DA prediction scores for each infant in the ED positive for either a non-RSV airway virus or bacterial infection. Error bars represent means and 95 % confidence intervals
