Distributions of cytokine values (log-transformed) in repeated assays over a brief period. OPG: A value below the limit of detection in the first assay was excluded. IL-17A: values below the limit of detection (all measurements in the fifth assay and four of the 15 measurements in the sixth assay) were excluded. The y-axes, except for IL-17A, are scaled to the ranges from the healthy volunteer measurements
