Abundance of six peptides in serum from patient samples. The abundance of each peptide (A), each protein (B), and combinations of peptides (C) was quantified in non-cancerous, benign ovarian condition (benign), early-stage HGSOC (early-stage), and late-stage HGSOC (late-stage) sera using the PRM assay developed in this study. The abundance indicates the on-column concentration based on a 10 µL injection volume. Statistically significant differences were obtained by non-parametric ANOVA. *, **, and *** indicate p < 0.05, p < 0.01, and p < 0.001 respectively
