Clinical characteristics of patients who had undetectable CMV VL at baseline.

ID = identity, CMV VL = cytomegalovirus viral load, ICU = intensive care unit, ET = early treatment,DT = delayed treatment, nt-LVL = non-treatment and low viral load, ND = not done, N/A – ganciclovir was not administered as some of these patients were admitted at a time when a 10000 copies/ml threshold for CMV treatment was used, LDL = lower than detectable limit. For consistency, sample collection dates were used for CMV VL results.
