2. Fig 1
The respiratory disturbance index (events per hour) in REM plotted against the respiratory disturbance index in NREM for each individual patient in the study. Those above the diagonal represent patients with a higher RDI during REM and vice versa.

3. Fig 2
The minimum blood oxygen saturation (per cent) by pulse oximetry in REM plotted against the minimum saturation in NREM for each individual patient in the study. Those above the diagonal represent patients with a higher saturation nadir during REM and vice versa.

(a) The difference between the NREM and REM respiratory disturbance indices (events per hour) for each patient plotted against his/her age in years. (b) The difference between the NREM and REM saturation nadirs (per cent) for each patient plotted against his/her age in years.

(a) The difference between the NREM and REM respiratory disturbance indices (events per hour) for each patient plotted against his/her body mass index (kg m−2). (b) The difference between the NREM and REM saturation nadirs (per cent) for each patient plotted against his/her body mass index (kg m−2).
