Figure 1 The 2-step regimen. Total body irradiation dose is 1.5 Gy per fraction, for a total dose of 12 Gy; CY dose is 60 mg/kg/day. Tacrolimus (Tacro) and mycophenolate mofetil (MMF) are initiated on day −1 for GVHD prophylaxis.

Figure 3 CMV reactivation and day +90 immune reconstitution. Patients with CMV reactivation had higher numbers of CD3/4, CD3/8, and NKDim cells at day +90 than patients without CMV reactivation. Differences were the greatest in the CD3/8 populations (P = .000, Mann-Whitney).
