Quantile plots of the corrected difference in observation frequency (Delta) and Chi Square values of the ovarian cancer (i.e. disease treatment) versus control as indicated. The difference of ovarian cancer (n ≥ 10) versus each of the female normal (n ≥ 5) using the Quantile plot tended to zero (see red line). Similar results were obtained by comparison to breast cancer or other controls (not shown). a Tryptic peptide corrected difference (delta) in observation frequency; b tryptic peptide Chi Square χ²; c tryptic and/or STYP the corrected difference (delta) in observation frequency; d tryptic and/or STYP peptide Chi Square χ²
