Log2 expression values were median centered (median of CD34+ = 0). All ALL: combined statistics with no subgroup analysis; T-ALL: T-cell ALL samples; B-ALL: B-cell ALL samples; Ph+ALL: all ALL samples expressing the Philadelphia chromosome; Ph−ALL: samples not containing the Philadelphia chromosome; SD: standard deviation; >norm (%): percentage above values within the 95% confidence interval based on the range of expression of the normal CD34+ cells; <norm(%): percentage below values within the 95% confidence interval based on the range of expression of the normal CD34+ cells; = norm (%): percentage equal to values within the 95% confidence interval based on the range of expression of the normal CD34+ cells; Obs Num: total observed cases per subgroup.
