Figure 1
Platelet counts in patients before and on treatment with thrombopoietic agents. Platelet counts are shown for the same day that blood was sampled for immunologic analysis. Platelet counts of patients on treatment (■) were statistically higher (P = .002) compared with before treatment (●). Median pretreatment count was 22 × 109/L, interquartile range 11 to 30 × 109/L versus 105 × 109/L, interquartile range 44 to 243 × 109/L on treatment group.
