Box plots for IQ and age-and-sex–adjusted BPASS traits. A = 297 affected children; U = 54 unaffected children; P = 343 parents. Each box shows lower quartile, median, and upper quartile. The whiskers extend to the most extreme data point that is no more than 1.5 times the interquartile range from the box.
