Total ranges of immunomodulatory and reference gene expression (qRT-PCR study). The total range of gene expression is represented by box and whisker plots for immunomodulatory genes (blue) and reference genes (gold), for 28 subjects at four time points. For each gene, the median is indicated by a horizontal line, the boxes indicate the range between the 25th to the 75th percentile, the whiskers indicate the range containing 1.5 times the interquartile range, and circles above the whiskers indicate outliers. Values beyond the range included by the whiskers are indicated as individual points. For ICAM1, three measurements were below the limit of quantification (Ct > 37).
