Table 5.

The five Leicester Cough Questionnaire (LCQ) questions, which showed the closest associations with repetitive (≥3 during the last 12 months) doctor’s consultations among participants with current cough (n=975), according to the Mann-Whitney test z-score. The question with the strongest association is uppermost

*Domain indicates the LCQ domain (Psy=psychological, Phy=physical, soc=social). The scale in each question is 1–7 with a lower value indicating more severe impairment. The figures are means and 95% CI. P<0.001 between the subgroups in all presented questions.
