Fig. 2From: Factors associated with recurrence and mortality in central line-associated bloodstream infections: a retrospective cohort studyPredicted 60-day recurrence-free survival by antimicrobial treatment duration. The relationship between the number of days of effective antimicrobial treatment received and the predicted probability of 60-day recurrence-free survival is shown, based on the Cox proportional-hazards model described in Table 2. The shaded area indicates the 95% confidence interval. Other covariates in the model were adjusted to their median values: age 55 years, Sequential Organ Failure Assessment score 6, male sex, no immunosuppression, all central lines removed, and no high-risk organism present.
