| Secondary | Analysis of Covariance for Three Patterns of Dose Response Using the Change From Baseline in Platelet Counts (Baseline Platelet Counts as Covariate) | Exploratory analysis was conducted to see a dose response/trend when a dose goes high with the changes from baseline in platelet counts (12.5 mg, 25 mg, and 37.5 mg) on Day 15 of each subject. The data were analyzed with baseline of platelet counts as covariate for the following dose response pattern using contrast: (1) linearity, (2) saturation at the medium dose, (3) onset of response at the high dose. | | Posted | | Mean | 95% Confidence Interval | 10^9/Liter | | Baseline, Day 15 | | | | ID | Title | Description |
