Figure 1.
Score scatterplot of the projection to latent structures discriminant analysis (PLS-DA) model for patients with bronchiolitis versus healthy controls. tp and to are the predictive and nonpredictive latent variables, respectively, obtained by posttransformation of the PLS-DA model. Gray circles represent urine samples from the bronchiolitis group, and white circles represent those from the control group. The samples from the bronchiolitis group lie in the region with a negative tp value, while those from the control group show positive tp values.
