Summary

Researchers are developing and testing a new questionnaire to objectively measure how severe a person's chronic cough is. The study will enroll 100 adults, including both chronic cough patients and healthy volunteers. The goal is to create a reliable tool that doctors can use to assess cough severity and track changes over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this questionnaire could give doctors a reliable way to measure cough severity, helping to improve patient care and future research.
What could go wrong
This is an early-stage validation study, not a treatment trial. The questionnaire may not prove accurate or useful in all patients.
