Correlation between response to the different drug regimens and the clinical characteristics of the patients. For 26 of the 35 patients reported in Table 4 we calculated odd ratios (ORs) with 95% confidence intervals (error bars) estimating the probability for each treated colony to express BCR-ABL compared with untreated colonies, and correlated the results to 11 clinical characteristics. An OR of 1 means no effect; an OR greater than 1 means an increased probability to express BCR-ABL, while an OR less than 1 indicates a reduced probability to express BCR-ABL. Treatment conditions are indicated on the bottom.
