2. Figure 1
Principal components 1 and 2 in polycystic ovary syndrome (PCOS) and control subjects compared with subjects in datasets of known ethnicity. (A) Individual PCOS subjects (case subjects; red) and control subjects (blue) plotted as a function of principal components 1 and 2. PCA = principal component analysis. (B) Data from women with PCOS (case subjects; red circles) and control subjects (blue circles) plotted as a function of principal components 1 and 2 and superimposed on data from populations of known ethnicity. The PCOS subjects cluster statistically closer to the Tuscan and Italian populations, whereas the control subjects cluster closer to the French and Orcadian populations (P<.002). (C) Map indicating location of the populations of known ethnicity.
