The table above illustrates the values for the 6 oximetry variables for each subject.
Median values are displayed in bold, minimum and maximum range in square brackets. Curly braces {} denote the overall trend of the variable throughout the study: ↑, trend increased; ↓ trend decreased; →, no change in trend. ODI 3%, ≥3% arterial oxygen desaturations/h; ODI 4%, ≥4% arterial oxygen desaturations/h; min dip SpO2, minimum dips in oxygen saturations.
