TABLE 7.

Adjusted odds ratios for significant factors for preventing severe complications in patients with liver abscess due to K. pneumoniae^a:

Factor	Adjusted odds ratio	95% CI
Platelet count > 100 × 109/liter	0.03	0.004-0.28
Alkaline phosphatase < 300 U/liter	0.19	0.04-0.78
No gas formation in abscess	0.2	0.05-0.92
APACHE III score < 40	0.07	0.01-0.39
Extended-spectrum cephalosporin treatmentb	0.01	0.001-0.12
Early drainagec	0.11	0.02-0.53

^aIn addition to the six factors in this table, age, sex, history of diabetes and peptic ulcer, tachypnea, tachycardia, albumin, blood urea nitrogen, and creatinine levels, and large abscess were all included in the logistic regression analysis. They were all eliminated in the final model.

^bPatients received an extended-spectrum cephalosporin for at least 3 days within the first 5 days of hospitalization.

^cPatients received early drainage within 3 days of diagnosis.
