2. Fig. 1
Frequency of human leukocyte antigen (HLA) sensitization in left ventricular assist device (LVAD) recipients. (PRE-LVAD = before LVAD; PEAK LVAD = peak level of panel-reactive antigen [PRA] during LVAD support; LVAD TX = at time of transplantation.)

3. Fig. 2
Mean panel-reactive antigen (PRA) levels showed significant increase during left ventricular assist device (LVAD) support and at the time of transplantation (TX).

Effect of leukocyte depletion (LD) and cytomegalovirus (CMV) status of transfused platelet (PLTS) concentrates on mean panel-reactive antigen (PRA) levels during left ventricular assist device (LVAD) support and at the time of transplantation. (NEG = negative; ? = unknown status.)
