  1. Data are presented as median (25th − 75th percentile) in pg/mL. p-values are calculated with a Mann Whitney U test and adjusted by the Benjamini-Hochberg (BH) method for multiple comparisons of all 42 analytes in order to calculate a false discovery rate, or q-value. 16 analytes met criteria for significance of q < 0.05. The following 5 cytokines were excluded from analysis because > 70% of the values were below the lower limit detection for the Luminex assay: GM-CSF, IL3, IL22, IL17A, TNFβ.
