In this multinational, noninferiority trial that included more than 3,600 hospitalized patients with bloodstream infections from various pathogens and infectious syndromes, seven days of antibiotic therapy was noninferior to 14 days with respect to death from any cause by 90 days. Patients were excluded if they had severe immunosuppression or foci requiring prolonged treatment, or if their blood cultures yielded Staphylococcus aureus or possible contaminants. Various secondary outcomes were similar between the two groups.
