| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Measured differences | The authors reported differences in selected autonomic, immune and cerebrospinal-fluid measures. | |
| Tilt-table testing | No group differences in rates of orthostatic hypotension, excessive orthostatic tachycardia or symptoms ending the test. |
