Boxplot showing serum 25(OH)D concentrations by ancestry. The boxplot presents five statistics: the top of the box represents the 75th percentile, the line within the box represents the median and the bottom of the box represents the 25th percentile, while the whiskers correspond to the minimum and maximum values that are not outliers. The points above or below the whiskers represent outliers. The asterisk (*) on the plot corresponds to an outlier whose serum levels were the highest reported in this study (110 nmol/L).
