Fig. 2From: Do fragments and glycosylated isoforms of alpha-1-antitrypsin in CSF mirror spinal pathophysiological mechanisms in chronic peripheral neuropathic pain? An exploratory, discovery phase studyLoadings column plot for healthy controls (a) (n = 11) and neuropathic pain patients (b) (n = 11). Each column represents the value of the loading p [1] of that particular protein in the principal component analysis (PCA) model. The columns of the two fragments of alpha-1-antitrypsin (AT) that the present paper focuses on (I_AT111 and AT5106) are depicted in black and white, respectively. Other protein abbreviations are angiotensinogen (AG), haptoglobin (HG), and pigment epithelium-derived factor (PEDF). The number after each protein name abbreviation corresponds to the spot numberBack to article page
