Maybe USA people DO cough differently ?!, page-17

This was pointed out previously but RAP did indicated they used symptoms as input for all the other respiratory diseases except croup (only cough) in the last AUS results but didn't mention this for the US results so possible only cough audio was used as input. Also results in the past included other subsequent age and/or gender and/or symptom accuracy were higher with their cough only accuracy.
Race isn't an input, as indicated the PoC was done in Indonesia, then further studies done in Australia.

1. ResApp algorithm includes cough audio and patient reported symptoms as input.
2. ResApp algorithm includes cough audio as input only.
