The median predictions followed the trend of your relationships, and the majority of the observed response proportions were covered by the 90 intervals on the model predictions. The predicted median response prices (with 90 prediction intervals) for sufferers treated with dasatinib 100 mg after day-to-day, 50 mg twice every day, 140 mg after each day, and 70 mg twice day-to-day had been 53 (27 ?three ), 20 (7.7 ?0 ), 60 (47 ?0 ), and 47 (27 ?7 ), respectively. This evaluation indicates that, in general, the model described the relationship among MCyR rate and every predictor reasonably nicely, although response rate inside the 50 mg twice every day group was underpredicted by the model.E for safety: pleural effusionOf the 567 patients integrated within the E analysis with the Phase III dose-optimization study, 94 had pleural effusions. Pleural effusion prices have been 11.0 (one hundred mg when daily), 16.two (50 mg twice everyday), 17.7 (140 mg as soon as day-to-day), and 22.0 (70 mg twice each day). The Cmin.
