  1. Abbreviations: SAP systolic arterial pressure, FI-MDS minimum data set derived frailty index. asample size for these variables, n = 55. Bold data indicate statistically significant differences. Italicised data indicate differences that did not quite achieve statistical significance
  2. Frailty was correlated with both retrospective and prospective falling rates, the initial orthostatic decrease in blood pressure, and 3-year mortality. The prospective falling rate was correlated with the retrospective falling rate, the magnitude of the orthostatic decrease in blood pressure, and the initial recovery in blood pressure. The outcome of mortality was considered met in participants who had died after 36 months (n = 69) or who had been discharged to a higher level of care (n = 6)
