of assessing the cough severity mainly include the cough scores, visual analogue scale (3) and QoL questionnaires like the Leicester cough questionnaire (LCQ) (4), coughspecific quality of life questionnaire (CQLQ) (5) etc. They are easy to score and also practical for a longitudinal comparison in clinical practice.
