Impact of smoking cessation on non-alcoholic fatty liver disease prevalence: a systematic review and meta-analysis.

Objectives: The negative effects of smoking on numerous cardiovascular and metabolic diseases have been widely acknowledged. However, the potential effect of smoking cessation is relatively unelucidated. The objective of this study is to explore whether the prevalence of non-alcoholic fatty liver disease (NAFLD) in former smokers differs from the prevalence in current smokers.
