Concentrations of immune mediators. Concentration ranges for all immune mediators measured in at least 2 studies. The box-and-whisker plots show concentrations including all studies and sample types. The middle bar shows the median, with the edges of the box ranging from the 25th to the 75th percentiles and the whiskers ranging from the 5th to the 95th percentiles. The percentages shown at the right reflect the percent of samples detected above the lower limit of detection
