Quantifying test-retest variability of natural and suppressed citric acid cough thresholds and urge to cough ratings
ConclusionsNatural and suppressed cough thresholds and UTC ratings are subject to test-retest variability. These data are important for the use of citric acid CRT as an outcome measure in longitudinal cough research, as they facilitate interpretation of whether changes in citric acid cough thresholds across days reflect true changes in cough sensitivity, rather than an artefact of repeating the test.
