Relationship between post-transfusion in vivo vs in vitro data. (A) Poststorage platelet recoveries vs in vitro measurements. (B) Poststorage platelet survivals vs in vitro measurements. ●, data for Haemonetics platelets in CLX bag; ○, in CPP bags; ▪, for Trima platelets in Terumo BCT bags; □, in Haemonetics CLX bags; ▲, for Spectra platelets in Terumo BCT bags; and △, in Haemonetics CLX bags. The regression lines for the data are shown as the hatched lines, and the r² values are given on the figures.
