  • CI: confidence interval; CEI: cumulative exposure index. #: n = 5,545; : adjusted for smoking status; +: time since first exposure (TSFE) and CEI were used, but TSFE was not significant in the models and was removed; §: TSFE, intensity and duration of exposure were used, but neither TSFE nor duration of exposure were significant in the models and were removed; ƒ: trend test.
