Figure 1 . Kaplan-Meier survival analysis of entire cohort with a deep sternal wound infection with 95% confidence banks.
Figure 2. Kaplan-Meier survival analysis after deep sternal wound infection, stratified by time of onset after cardiac surgery, (<31 days, solid line) versus late (>30 days, dashed line).
Figure 3. Forest plot of multivariable logistic regression model of late (>30 days) or early (≤ 30 days) onset of deep sternal wound infection after cardiac surgery. Odds ratio (OR) > 1.0 favors late infection (bars represent 95% confidence intervals).
Figure 4. Forest plot of propensity adjusted multivariable analysis of mortality. Hazard ratio (HR >1.0 associated with increased mortality (bars represent 95% confidence intervals). Abbreviations: NPWT = negative pressure wound therapy.
