Unadjusted in-hospital mortality as a function of initial systolic BP category in patients older than 70 years of age

Initial systolic blood pressure (mmHg) before ED treatment
Patients, n (821)96154212359
Absolute mortality, n20221817
Mortality per category, % (95% CI)20.8 (16.7 to 24.9)14.3 (11.5 to 17.1)8.5 (6.6 to 10.4)4.7 (3.6 to 5.8)
  • With every increase in systolic blood pressure  category, unadjusted mortality almost linearly decreases. In-hospital mortality is represented as n (%) with 95% CI. The number inside the brackets indicates the number of patients included in the analysis.
