Serum levels of ENA-78 in autistic patients and healthy controls. Horizontal bars indicate the median values. ENA-78, epithelial cell-derived neutrophil-activating peptide-78. The boxes enclose the interquartile ranges (IQR) which are between the 25^th and 75^th percentiles. The horizontal line inside the box represents the median and the whiskers represent the non-outlier (between 1.5 and 3 IQR above the 75th percentile) or extreme (more than 3 IQR above the 75th percentile) maximum and minimum values of serum ENA-78 levels. The small open and black squares represent the outlier (between 1.5 and 3 IQR) or extreme values (more than 3 IQR), respectively of serum ENA-78 levels in autistic children.
