Short-term remission rate according to cytomegalovirus antigen status. Kaplan-Meier curves for the rate of induction of remission. A: The remission rate from the day of starting the remission-induction therapy; B: The remission rate from the day when the status of cytomegalovirus (CMV) antigen was determined. Both curves show the better clinical course in the CMV-negative group (P = 0.0006 and P = 0.03, respectively, Log-rank test). The median number of days to remission from the start of the treatment based on our strategy was significantly greater for patients in the CMV-positive group than for patients in the CMV-negative group (21 d vs 16 d, P = 0.009, Mann-Whitney U test).
