| TT | FT | |||
|---|---|---|---|---|
| B (95% CI) | Adj R2 | B (95% CI) | Adj R2 | |
| AHI | -0.078 (-0.112 to -0.044) | 0.162 | -2.071 (-2.961 to -1.182) | 0.165 |

p values in all models are < 0.05, AHI, apnea-hypopnea index; BMI, body mass index; siMS, continuous metabolic syndrome score; SBP, systolic blood pressure; FPG, fasting plasma glucose; Tg, triglycerides; HDL, high density lipoprotein; ODI, oxygen desaturation index.
