Fig. 3From: A multiplatform metabolomic approach to characterize fecal signatures of negative postnatal events in chicks: a pilot studyDiscriminant GC-MS fecal metabolites and score plot based on OPLS-DA model. In the score plot, the individuals from the delayed (D) and control (C) groups are represented by orange triangles and light blue circles, respectively. The bar plot represents the contributions of the variables (a negative contribution score indicates a contribution of the variable to the delayed group while a positive score is indicative of a contribution to the control group) and their importance in projection (VIP) in the OPLS-DA model. The descriptive and predictive performance characteristics of the models are R2Ycum = 0.45 and Q2cum = 0.2Back to article page
