Multivariate logistic regression—WBC as a factor for true BSI

Variable	Adjusted odds ratio (95% CI)	p value
WBC Count “high” (15–19.9 × 109/L)	2.56 (0.950–6.88)	0.06
APACHE II score	1.07 (1.03–1.11)	< 0.01
(Intercept)	0.010	< 0.01

Stepwise logistic regression had entry at significance of 0.05 and removal at significance of 0.1

Four variables were included in the stepwise regression analysis: age, APACHE II score, COVID-19-associated med: glucocorticoids, and WBC count “high” (15–19.9). Age was removed in step 1 at 0.23 significance, and COVID-19-associated med: glucocorticoids was removed in step 2 at 0.18 significance
