Box plots represent relative quantification of two haptoglobin peptides bearing tri-antennary glycopeptides and their fucosylated forms for each patient group. Peak intensities of the 366 transition were used for calculation of the ratio of glycopeptides for the MRM quantification (shown on the left). Intensities of the XIC of the third isotope of each glycopeptide were used for calculation of the ratios of fucosylated and non-fucosylated glycopeptides or the ratio of tri-antennary and bi-antennary glycopeptide for the FT-ICR quantification (shown on the right). The numbers above each box plot represent p-values.
