Analysis of median time to documented clearance of VRE colonization. The X-axis represents time (in weeks) from documented colonization and the Y-axis represents the proportion of patients with documented clearance of colonization. This proportion included the initial subject population minus those lost to follow-up. Each circle represents a single study (A-M). The size of the circle is inversely proportional to its standard error. The line represents the model-fitted clearance over time, with 50% of subjects clearing VRE at 26 weeks from time of documented colonization (*).
