Average parameters of sigmoidal baroreflex curves for LZRs and OZRs
| n | MAP50 (mmHg) | Slope (%/mmHg) | L Plateau (%) | Range (%) | |
|---|---|---|---|---|---|
| ADNA | |||||
| LZR | 11 | 144 ± 3 | 20 ± 2 | −7 ± 3 | 249 ± 21 |
| OZR | 9 | 139 ± 3 | 16 ± 2 | 1 ± 5 | 232 ± 43 |

| LZR | 11 | 165 ± 2 | −13 ± 1 | −6 ± 5 | 129 ± 10 |
| OZR | 8 | 161 ± 7 | −8 ± 2* | 45 ± 4* | 56 ± 4* |
Values are mean ±s.e.m. ADNA, aortic depressor nerve activity; SNA, sympathetic nerve activity; MAP50, MAP at the midpoint of the curve; L Plateau, lower plateau; Range = upper plateau – lower plateau.
