We found that 18 of the 108 proteins investigated were influenced by storage time (Supplementary Table 1, nominally significant, p < 0.05), and one protein (Cancer antigen 125; CA-125 also known as Mucin 16) remained statistically significant after correction for testing of multiple hypotheses (Bonferroni, p < 0.05/108 = 4.6 × 10 − 4 ).
