Hemostatic function recovery rate depends on platelet function, not count, in transfused platelet concentrate. (Upper left) Correlation between the difference in the AUC of the T-TAS of blood collected before versus after platelet transfusion (ΔAUC of T-TAS in patients) and the AUC of the T-TAS of platelet concentrate (PLTc); Pearson’s correlation coefficient (r) = 0.748, P = 0.021. (Upper middle) Correlation between the ΔAUC of the T-TAS in patients and the AUC of the Multiplate Analyzer; r = 0.535, P = 0.138. (Upper right) Correlation between the ΔAUC of the T-TAS in patients and the platelet number of the PLTc; r = 0.129, P = 0.740. (Lower left) Correlation between the AUC of the T-TAS of PLTc and the platelet number of the PLTc; r = 0.298, P = 0.436. (Lower middle) Relationship between the AUC of the T-TAS and the storage period of PLTc (days between blood donation and transfusion). (Lower right) Relationship between the ΔAUC of the T-TAS in patients and the storage period of PLTc. The data for one of the 10 PLTc were unavailable, and thus nine cases were analyzed
