REI3: Respiratory Event Index (REI) computed over all respiratory events, defined as apneas or hypopneas with at least 50% cannula flow reduction for a minimum duration of 10 s with >=3% oxygen desaturation; REI0 REI computed over all respiratory events regardless of oxygen desaturation; HB hypoxic burden; avgEventLength the average length of apnea and hypopnea events (combined); minSpO2 minimum oxyhemoglobin saturation during sleep; avgSpO2 average oxyhemoglobin saturation during sleep; Per90 percentage of sleep time with oxyhemoglobin saturation below 90%; SDBPC1 the first principal component of the seven sleep disordered breathing traits included in the principal component analysis; SDBPC2 the second principal component of the seven sleep disordered breathing traits included in the principal component analysis.
