ALB and susceptibility to pneumonia measurement: The developed final model contained the effects of CrCL and infection sites (pneumonia [CREDIBLE-CR and APEKS-NP studies], BSI/sepsis, cUTI [CREDIBLE-CR study], or cUTI/AUP [APEKS-cUTI study]) on CL, body weight on the volume of distribution in the central and peripheral compartments (V1 and V2, respectively), albumin concentration (ALB), and any of the infection sites on V1.
