Hierarchical multiple logistic regression analysis was performed. Model 1 included age, sex, BMI, hyperosmolar solutions.
C-reactive protein. Model 2 included Model 1 and using polyurethane catheter. Model 3 included Model 1 and ultrasonography assist. Model 4 included all variables.
LL, lower limit; UL, upper limit; OR, odds ratio. Model 4: Hosmer-Lemeshow test, p = 0.19.
