Ratios of the levels of representative proteins [Q5VY30_HUMAN—plasma retinol-binding protein; PON1_HUMAN—serum paraoxonase arylesterase; A1AG2_HUMAN—alpha-1-acid glycoprotein; APOA2_HUMAN—apolipoprotein-A-II; CLUS_HUMAN—clusterin; APOC3_HUMAN—apolipoprotein C III; and F5GXS0_HUMAN—C4b B, detected in unbound-PI (A) and bound-PII fractions (B) of breast cancer patients and healthy controls]. The different breast cancer stages are represented as follows: light gray (I—early), dark gray (II—intermediate), and black (III—advanced).
