Forward stepwise regression models for the changes in insulin sensitivity
| Adjusted R2 | Estimate (se) | p-value | |
| After 1 week of nCPAP# | |||
| Changes in urinary normetanephrine, nmol·mmol−1 creatinine | 7.4% | -0.184 (0.078) | 0.023 |
| After 12 weeks of nCPAP treatment¶ | |||
| BMI<25/BMI≥25 kg·m−2 | 22.8 % | 2.928 (0.962) | 0.005 |
Independent variables considered were: age, waist circumference, body mass index (BMI) <25/BMI≥25 kg·m−2, sleep parameters at baseline (apnoea/hypopnoea index, arousal index, duration with O2 saturation <90% and minimum O2 saturation), changes in urinary norepinephrine, normetanephrine, epinephrine and metanephrine. nCPAP: nasal continuous positive airway pressure. #: n = 57; ¶: n = 29.
