FIG 4.

Forest plots of risk factors for overall mortality within 100 days after the BAL. (A) Model 1 demonstrates the results of an adjusted model in which the human herpesvirus (HHV)-6B⁺ BALF variable was incorporated as positive or negative. (B) Model 2 demonstrates the results of an adjusted model in which the HHV-6B⁺ BALF variable was incorporated in quartiles of viral load. (C) Model 3 demonstrates the results of a univariate analysis of LRTD categories stratified by HHV-6B⁺ BALF; bacterial pneumonia without HHV-6B detection in the BALF is the referent (ref) for all other categories. The variables shown in the figure were all the variables included in the final models. aHR, adjusted hazard ratio; ALC, absolute lymphocyte count; BAL, bronchoalveolar lavage; BALF, bronchoalveolar lavage fluid; GVHD, graft-versus-host disease; HCT, hematopoietic cell transplantation; IPS, idiopathic pneumonia syndrome; LRTD, lower respiratory tract disease.
