Multivariate analysis
Age	0.13	1.1 (0.97–1.24)
Dexmedetomidine	0.045	9.75 (1.05–90.8)
Beta-blocker	0.36	0.69 (0.32–1.51)

Univariate analysis was conducted by Fisher’s exact test. Multivariate logistic regression analysis was conducted using age, Dex, and beta-blocker, extracted because their p values in univariate analysis were not exceeding 0.15
BMI body mass index, CRP serum level of C-reactive protein, APACHE II score Acute Physiology and Chronic Health Evaluation II score, SOFA score Sequential Organ Failure Assessment score
