Data were presented as n (%) or mean ± standard deviation (SD; range) and analyzed using the Statistical Package for Social Sciences 19.0 software. In the analysis of the risk factors for CRKP infection/colonization and mortality, a univariate logistic regression analysis was performed. To identify the independent risk factors, variables with P < 0.05 in the univariate analysis were included in the multivariate logistic regression model and analyzed using backward stepwise regression. Odds ratio (OR) and a 95% confidence interval (CI) were also calculated. For all statistical analyses, P < 0.05 indicated a statistical significance.
