Additional cardiovascular autonomic function indices: methodological details and references

Impaired deep breathing	Reduced deep breathing ratio compared to age- and sex-matched healthy controls of our lab [22, 25]
Impaired valsalva maneuver	Reduced Valsalva ratio compared to age- and sex-matched healthy controls of our lab [22, 25]
Delayed orthostatic hypotension	BP fall > 20 mmHg systolic or > 10 mmHg diastolic occurring later than 3 min after begin of the orthostatic stress [26]
Non-OH BP falls	BP falls at 3 min of head-up tilt or active standing < 20 mmHg systolic or < 10 mmHg diastolic
