Ann: ResApp Provides SMARTCOUGH-C-2 Study Update, page-2

The study is recruiting to plan, with 1,277 patients recruited as of 30 May 2018. The incidence of
the various diseases among study participants has been as expected which should ensure the
study generates statistically strong results. Independent quality assurance of the cough audio
recordings has been performed on-site weekly, as per the study protocol, with a sample of the
audio recordings also being reviewed directly by ResApp. Only approximately 1% of recordings
have been found in the quality assurance process to be unacceptable.
