  • Data are presented as mean±sd

  • ΔPs: difference between highest systolic blood pressure value after, and lowest value during, apnoeic/hypopnoeic events

  • ΔPd: difference between highest diastolic blood pressure value after, and lowest value during, apnoeic/hypopnoeic events

  • ΔSa,O2: difference between highest oxyhaemoglobin saturation value preceding and lowest oxyhaemoglobin saturation value following apnoeic/hypopnoeic events
