Abbreviations: CI: confidence interval; Up-BEI: up-events baroreceptor effectiveness index; Down-BEI: down-events baroreceptor effectiveness index; Total-BEI: total-events baroreceptor effectiveness index; HUT60: head-up tilt at 60°; OscSBP: oscillometric systolic blood pressure; OscDBP: oscillometric diastolic blood pressure; ΔSupine-HUT60 represents the difference between the variables averaged over 5 minutes of HUT-60° and the variables averaged over 5 minutes of supine recording.
