Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to investigate the biological determinants of sputum rheology variations.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Secondarily, this study aims to compare rheology parameters between different chronic airway disease sub-populations.
