Multivariate logistic regression analyses for endpoints 30-day mortality, severe sepsis or septic shock and disseminated disease.

§Three patients were lost to follow-up.
&Mandatory variable.
#Due to an extremely high correlation of blaI and blaR (contingency coefficient 1.0 of blaR with blaZ), only blaZ was included in the multivariate logistic regression model (endpoint 30-day mortality).
§Due to a high correlation of sed/sej/ser and aadD (contingency coefficient 0.71), only sed/sej/ser was included in the multivariate logistic regression model (endpoint severe sepsis/septic shock). If aadD is included instead, results are OR 4.23 (95% CI 0.91–19.61, p = 0.07) for aadD and OR 1.80 (95% CI 1.04–3.10, p = 0.03) for fosB.
†Due to a contingency coefficient of 1.0 of sed, sej, ser, only sed was included in the multivariable logistic regression model (endpoint disseminated disease).
‡If 22 SAB cases with initiation of adequate antibiotic therapy ≥3 days after onset of SAB were excluded from the analysis CC15 exhibited a marginally significant effect with OR 2.81 (95% CI 1.0–7.91, P = 0.05) whereas mecA lost its significant impact (OR 3.35, 95% CI 0.79–14.21, p = 0.10). For the other endpoints no significant changes were observed.
