  • The number and percentage of emergency department admissions for each category are shown in the above table, along with the percentage that ended in death. The unadjusted OR along with lower and upper limits of the 95% CIs are shown in each row along with the significance for the test and significance for the trend within each category, if appropriate. Note that this analysis includes only those admissions where complete records of all potential confounders were kept.

  • *Patients under the age group 45–49 were used as the baseline group for calculation of ORs.
