Evaluation of the mean daily fall of the platelet count after medium, high, and very high doses of platelets in patients without clinical factors favoring platelet consumption. * In seven patients, the platelet counts on days 3, 4, and 5 after medium, high, and very high doses were not relevant because the patients were retransfused on the day before; so in these patients, the counts on these days were estimated and extrapolated from the fall in the platelet count in the previous days.
