OPAL1 expression in different ALL subtypes.OPAL1 expression was compared in a total of 180 children with ALL treated according to COALL protocols (A), and in a total of 257 children with ALL treated according to St Jude protocols (B). OPAL1 expression is shown in log2-transformed scaled arbitrary units (AU). The medians (horizontal lines), the 25th and 75th percentiles (boxes), the ranges (bars), and the outliers (open circles) are shown. **Indicates P < .001, determined by the Mann-Whitney U test.
