weeks to clearance, % cleared

See table 3 of study.

In healthcare settings, pooled ESBL/CRE colonization rates:

Without intervention 76.7% (95% CI 69.3%–82.8%) at 1 month to 35.2% (95% CI 28.2%– 42.9%) at 12 months of follow-up.

With decolonization: 37.1% (95% CI 27.5%–47.7%) at end of therapy and 57.9% (95% CI 43.1%–71.4%) at 1 month.

Among community dwellers, ESBL colonization decreased from 52.3% (95% CI 29.5%–74.2%) at 1 month to 19.2% (95% CI 9.7%–34.4%) at 6 months.
