PR, prevalence ratio. PRa, adjusted prevalence ratio. CI 95%, 95% confidence interval. The multifactorial analysis using the Cox regression model indicated that patients admitted from the emergency (HR = 0.40, ) and patients with an altered glycemic index (HR = 1.68, ) were more likely to die in the ICU (Table 3).
