Box plots of log distance from composite control profiles, by case/control status and week.

All TCRBV families are included. In each box plot, median values are marked by the notched horizontal bar. The box extends from the lower to the upper quartile of the distribution, thus giving the interquartile range (IQR). Dashed vertical lines extend from each end of the box for at most 1 IQR, or to the most extreme value. Outliers more than 1 IQR from the ends of the box are marked. The continuous line connects the mean values at each time point.
