1H nuclear magnetic resonance (NMR) analysis. Orthogonal signal correction/principal component analysis (OSC-PCA) scores plot (left column) and loadings plots (right column) for Carr-Purcell-Meiboom-Gill (CPMG) 1H-NMR spectra of plasma from the four phenotypes of polycystic ovary syndrome (PCOS) patients (red squares) and controls (black triangles). (A) PCOS patients with hyperandrogenism (HA), anovulation (AO) and polycystic ovaries (PCO) (HA+AO+PCO) vs controls; (B) PCOS patients with anovulation and polycystic ovaries (AO+PCO) vs controls; (C) PCOS patients with hyperandrogenism and anovulation (HA+AO) vs controls; (D) PCOS patients with hyperandrogenism and polycystic ovaries (HA+PCO) vs controls.
