MDRO, multi-drug resistant organism.
a
Preterm infants were defined as those born at a gestational age of < 37 weeks (≤259 days).
b
Low birth weight infants were defined as those whose birth weight was < 2,500 g.
c
Advanced maternal age is generally considered as maternal age ≥ 35 years, so the cut-off value was determined by this.
d, f
The cut-off values were determined according to the relevant research results.
e, g
The cut-off values were determined according to the ROC curves.
