Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Devices - Standard AutoSet algorithm
Treatment: Devices - Modified AutoSet algorithm

Experimental: Unblinded Investigational Arm - Participants participated in an unblinded investigational phase of the trial prior to, and separate from, the single-blind cross-over phase of the trial. Data was collected from the his phase to aid the final development of the algorithm before proceeding to algorithm validation (ie. cross-over phase).

Active comparator: Standard AutoSet algorithm - Participants first received therapy with the Standard AutoSet algorithm for one night, and then received therapy with the Modified AutoSet algorithm (an AutoSet device with an algorithm developed for sleep breathing parameters specific to females) the following night.

Experimental: Modified AutoSet algorithm - Participants first received therapy with the Modified AutoSet algorithm (an AutoSet device with an algorithm developed for sleep breathing parameters specific to females) for one night, and then received therapy with the standard AutoSet algorithm the following night.


Treatment: Devices: Standard AutoSet algorithm
An AutoSet device with a standard algorithm developed for sleep breathing parameters that are specific to a particular gender.

Treatment: Devices: Modified AutoSet algorithm
An AutoSet device with an algorithm developed for sleep breathing parameters specific to females.
