Ann: Preliminary Top-line Results from SMARTCOUGH-C Study, page-304

People keep blaming noise, but in the announcement, it says they removed cases with "obvious background noise" from the final results. I suppose you could hope that it might work with non-obvious background noise, and that FDA will accept that standard. But I've lost hope in it. I'd only buy in with FDA approval, unless it can be marketed as a non-FDA-approved app.

From today's announcement:

"Patients which were identified as having obvious background noise have been excluded from this analysis."
