Evaluation of response after first–line treatment
Response rates were categorized as complete response, partial response,
or no response as follows: a platelet count lower than
30×109/L and absence of doubling from baseline was
considered as no response; a platelet count ≥30×109/L
but <100×109/L, and presence of a doubling
from baseline and absence of bleeding were considered as a partial
response; and a platelet count ≥100×109/L that
persisted for 3 months or longer was considered as a complete response
(1).
