Levels of three apolipoproteins were significantly increased in subjects with primary open angle glaucoma (POAG) compared to subjects with cataracts alone, the controls (C). The boxplots depict the distribution of protein levels in each group. Peptide spectrum match (PSM) values were used as semi-quantitative measurement of protein levels. The raw PSM values were log2 transformed to achieve a normal distribution
