§Formal statistical comparison not performed; corresponding CIs for the efficacy of best available therapy were used to provide context for descriptive estimates of ceftazidime–avibactam efficacy.
Patients in the mMITT population are defined as carrying a pathogen at the start of treatment and who received at least one dose of study drug.
Preferred best available therapy options for cUTI and cIAI were 5–21 days of treatment with meropenem, imipenem, doripenem, colistin and (for cIAI) tigecycline, administered intravenously, but any therapy, including combination treatment, was permitted.
*Consideration should be given to official guidance on the appropriate use of antibacterial agents
