Relative risks (95% CI) of any hypertension and BP non-dipping at 10 year follow-up by OSA status at baseline.
| BP parameters | OSA status at baseline | ||||
| % | Normal | Primary snoring | Mild OSA | Moderate/severe OSA | |
| Any hypertension | 17 | 1.0 | 1.9† (0.9 to 4.2) | 1.5 (0.7 to 3.0) | 2.5* (1.2 to 5.3) |
| Non-dipping | |||||
| SBP | 47 | 1.0 | 1.0 (0.8 to 1.4) | 0.8 (0.6 to 1.1) | 1.3* (1.0 to 1.7) |
