Smoking and the risk of atopic dermatitis: A two-sample mendelian randomization study.

ABSTRACT: Atopic dermatitis (AD) is considered to be one of the most common chronic diseases. It has been shown that smoking is associated with atopic dermatitis, but previous studies were mainly observational, which may be biased. The present study conducted a 2-sample mendelian randomization (MR) study to investigate the causal relationship. The present study obtained data on "ever smoked" and "atopic dermatitis" from published large-scale genome-wide association studies. The data were obtained from the UK Biobank and BioBank Japan. Three methods were used to perform a 2-sample MR analysis and also performed sensitivity analysis. The odds ratio and 95% confidence interval (CI) between smoking and AD calculated by MR-Egger regression, weighted median, and random-effects inverse variance weighting m
