Strength of OTF correlation as a function of ovarian gene expression shift The squared correlation coefficient (R²) for the 425 clones positively and negatively correlated (adjusted p<0.05) with ovarian tumor frequency (OTF) were plotted against their respective gene expression shifts. The shift is defined as the resultant of the subtracted gene expression log₂ ratios between extreme values (see Table 1 and Additional file 1, 2, 3 Results file).
