Incidence of platelet counts of <150,000 and <100,000 cells/mm3 at the visit on study days 7 to 9, at end of therapy (EOT) on study days 11 to 13, and at posttherapy evaluation (PTE) (7 to 14 days after EOT visit). BID, twice daily; LLN, lower limit of normal; PTE, posttherapy evaluation; QD, once daily. Treatment differences (shown over the connecting lines) reflect relative risk (RR) (95% CI). *, P < 0.05 (Fisher's exact test).
