Risk factors associated with admission to ICU
| Variable | Incidence | Unadjusted p value | Adjusted p value | Adjusted OR | 95% CI | |

| Incidence, number of patients for which this variable occurred. Unadjusted p value, univariate analysis. Adjusted p value, p value adjusted for all other variables. *Continuous variable so that the OR increases incrementally with each unit increase in variable; †median (SD); RR, respiratory rate; AMS, altered mental state; NA, not applicable | ||||||
