Multiple linear regression model for prediction of total testosterone (TT) and free testosterone (FT) for patients with BMI ≥ 40 kg/m2.
| TT | FT | |||
|---|---|---|---|---|
| B (95% CI) | Adj R2 | B (95% CI) | Adj R2 | |
| AHI | -0.070 (-0.109 to -0.031) | 0.129 | -1.995 (-2.971 to -1.019) | 0.164 |
| AHI adjusted for age, BMI, siMS score | -0.071 (-0.112 to -0.029) | 0.267 | -1.511 (-2.572 to -0.450) | 0.257 |
| ODI | -0.068 (-0.103 to -0.033) | 0.148 | -1.832 (-2.722 to -1.941) | 0.166 |
| ODI adjusted for age, BMI, siMS score | -0.069 (-0.106 to -0.032) | 0.284 | -1.379 (-2.341 to -0.417) | 0.258 |
p values in all models are < 0.05, AHI, apnea-hypopnea index; BMI, body mass index; siMS, continuous metabolic syndrome score; ODI, oxygen desaturation index.
