  • Data are presented as mean±sd or n %

  • Non‐OSA: subjects without obstructive sleep apnoea

  • OSA: subjects with obstructive sleep apnoea

  • BMI: body mass index

  • WHR: wais-to-hip ratio

  • U: urinary

  • MHMA: methoxy-hydroxy-mandelic acid

  • ACE: angiotensin-converting enzyme

  • CVD: cardiovascular disease

  • Non‐OSA was defined as apnoea-hypopnoea index<10·h−1 of sleep and OSA as apnoea-hypopnoea index≥10·h−1 of sleep

  • Catecholamines were measured per mol of creatinine

  • *: p<0.05

  • **: p<0.01

  • ***: p<0.001
