Factors influencing the incidence of chronic cough stratified by speaking a) English and b) French. Core incidence model adjusted for time to follow-up 1 (RR 1.08 (95% CI 0.94–1.25)), age, sex, smoking status, body mass index (BMI), provinces, self-reported general health, and respiratory airways diseases. Point estimate and error bars show the mean estimated relative risk with 95% confidence intervals. Numerical values are also shown.
