The inverse association of body mass index with lung cancer : Exploring residual confounding, metabolic aberrations and within-person variability in smoking
Background: The inverse observational association between body mass index (BMI) and lung cancer risk remains unclear. We assessed whether the association is explained by metabolic aberrations, residual confounding, and within-person variability in smoking, and compared against other smoking-related cancers. Methods: We investigated the association between BMI, and its combination with a metabolic
