Results of the multivariable analysis^a for factors associated with no urinary symptoms or signs at presentation among patients with bacteremic urinary tract infections.

Variables	Odds ratios (95% CI)	P value
Aged 75 years or older	2.16 (1.22–3.83)	0.008
Male sex	1.85 (1.09–3.13)	0.02
Dementia	2.19 (1.11–4.30)	0.006
Ischemic heart disease	0.43 (0.17–1.06)	0.07
Initial visit from symptom onset < 24 h	1.77 (1.07–2.95)	0.03

^aVariables were removed one-by-one using a backward stepwise method until all remaining variables had a p value of less than 0.2. The following variables were considered: age, sex, hypertension, dementia, stroke, ischemic heart disease, benign prostatic hypertrophy, diabetes, and time to initial visit from symptom onset. The level of statistical significance was set at 5%

CI, confidence interval.
