  • CI: confidence interval; TSFE: time since first exposure; CEI: cumulative exposure index. #: n = 5,545; : adjusted for smoking status and body mass index; +: TSFE, intensity and duration of exposure were used, but duration of exposure was not significant in the models and was removed; §: trend test.
