Research gaps

A controlled tape-alone natural-sleep trial with adequate multi-night precision.

A prospective baseline classifier that distinguishes compensatory oral breathing from modifiable mouth opening.

Durable functional benefit beyond snoring or a single apnea index.

Patient-level safety and intolerance rather than only tolerated-user efficacy.

Endpoint- and device-specific validation of consumer tracking, independent of treatment efficacy.

Boundary experiment

A preregistered randomized crossover of the exact tape product versus credible sham/usual breathing in adults with baseline mouth-breathing OSA, with multiple nights per phase, blinded PSG scoring, washout/order balance, predefined nasal and velopharyngeal strata, and complete intolerance/adverse-event capture.
