Responses were considered significant if they lasted for ≥8 weeks. Criterion for a platelet response was an absolute increase of ≥30 x 10\\^9/Liter platelet count for participants with a pre-treatment count of ≥20 x 10\\^9/Liter and for participants with a pre-treatment count of \\<20 x 10\\^9/Liter there must have been an absolute increase to ≥20 x 10\\^9/Liter and a ≥100% increase in pre-treatment level.
