Similarity in Signal Pattern Between Esophageal Pressure (PES) and Mandibular Jaw Movement (MM) for Different Types of Event

Event Types	Number of Events	Accelerometer MM	Gyroscope MM
Normal	1481	0.82 (0.81–0.84)	0.86 (0.85–0.88)
Respiratory effort-related arousal	874	0.84 (0.83–0.86)	0.85 (0.84–0.86)
Obstructive hypopnea	2519	0.85 (0.83–0.87)	0.87 (0.85–0.88)
Central hypopnea	1180	0.86 (0.84–0.88)	0.86 (0.84–0.88)
Obstructive apnea	100	0.90 (0.86–0.99)	0.89 (0.70–0.98)
Mixed apnea	655	0.99 (0.96–1.00)	0.92 (0.88–0.96)
Central apnea	1233	0.80 (0.79–0.81)	0.80 (0.78–0.81)

Notes: Values are median (95% confidence interval). Data are LCSS based similarity indices (2b) on 8042 pairs of MM (recorded by accelerometer or gyroscope sensors) and PES sequences, captured during normal breathing and the scored events.
