Serum cytokines and C-reactive protein of the study subjects according to serum zinc levels1.

1 Values are expressed as the mean ± SE. Mean values of IL-6, TNF-a, and CRP are back-transformed values. Mean values with different superscripts (a, b, c) within a row are significantly different among the three groups by Tukey’s multiple comparison test.2P for linear trend was determined by treating the median value of each group as a continuous variable using the general linear model (GLM).3P values, regression coefficients, and R2 were obtained by multiple linear regression analysis.Serum cytokines and C-reactive protein of the study subjects according to serum zinc levels1.
