Sorry Rappers, page-235

That's not how it works, firstly a patient can be diagnosis as having multiple respiratory diseases from the one cough sample.

So from the 400 example, they could count for 500 patients which accounted for 200 misdiagnosis of URTI, 200 for LRTI, 50 for Asthma/Reactive Airway, 10 for Bronchiolitis and 40 for Pneumonia or any other variation, hence, it was a total stuff up in the clinical trials datasets as no-one truly knows, RAP can only analysis what want wrong and redo the tests.
