Patient flow through study and stratification design for multivariable logistic regression analysis. Patients were first stratified in two groups according to initial SBP. A threshold of 120 mmHg is chosen to investigate whether a higher SBP threshold is needed for older patients. Patients were subsequently stratified into three fluid categories. Multivariable logistic regression analysis was performed per group to compare in-hospital mortality in older patients to younger patients, adjusting for confounders. Here, we show which groups were compared in the multivariable regression analysis of Table 2. The results of the multivariable analysis are shown in Table 2. Abbreviations: ED = emergency department, IV = intravenous, SBP = systolic blood pressure, L = liter, yrs = years
