ALB and depressive disorder: After correction for disease activity, overall levels of zinc (B = −24.28, pSimes<0.001) albumin fraction (B = −7.02, pSimes<0.001) and the percentage of the albumin fraction (B = −7.56, pSimes<0.001) were significantly lower and levels of α2 (B = 1.15, pSimes<0.001), β (B = 0.64, pSimes = 0.005) and γ (B = 2.02, pSimes = 0.028) fractions and those of the percentages of α2 (B = 0.18, pSimes<0.001), β (B = 1.23, pSimes = 0.002) and γ (B = 3.39, pSimes<0.001) fractions were significantly higher in subjects with a current/past depressive disorder.
