APACHE II score, mean, on admission	16.2	22.4	1.39 (−10.65-1.65)	0.009
SOFA score, mean, on admission	5.6	7.7	3.59 (−4.54 -0.27)	0.08
Vasopressor drug use	1 (2.6)	6 (28.6)	15.2 (1.68-137.15)	0.006
Mechanical ventilation	5 (12.8)	7 (33.3)	3.40 (0.92-12.55)	0.09

Univariable analysis demonstrated that risk factors associated with in-hospital mortality among patients with K. pneumoniae infection included receiving dialysis, elevated APACHE scores, and vasopressor drug administration. Figures in parentheses represent percentage values unless otherwise stated.
