PSG: polysomnography; AHI: apnoea–hypopnoea index; BMI: body mass index; WASO: wake after sleep onset; TST: total sleep time; REM: rapid eye movement; CRP: C-reactive protein; IL: interleukin; HDL: high-density lipoprotein; HOMA: homeostasis model assessment for insulin resistance; QUICKI: quantitative insulin sensitivity check index; SBP: systolic blood pressure; DBP: diastolic blood pressure; MAP: mean arterial pressure. Generalised linear model using gamma distribution and pairwise comparison through a Bonferroni test. MET was used as dependent variable. Statistical significance when p≤0.05.
