From: Metabolomics Profiling for Obstructive Sleep Apnea and Simple Snorers

Score plots of the orthogonal partial least-squares discriminant analysis model for the obstructive sleep apnea (OSA), simple snorers (SS) and control groups.
(A) The model parameters were: R2X = 0.104, R2Y = 0.384 and Q2Y = 0.088; (B) the model parameters were: R2X = 0.115, R2Y = 0.773 and Q2Y = 0.085; (C) the model parameters were: R2X = 0.090, R2Y = 0.722 and Q2Y = 0.263; (D) the model parameters were: R2X = 0.117, R2Y = 0.639 and Q2Y = 0.021.
