Letter: Comments on “Rural Residency has a Protective Effect and Marriage is a Risk Factor for NAFLD”

Dear editor, i was interested in the study entitled “rural residency has a protective effect and marriage is a risk factor for nafld”. i believe the current paper provides an important contribution to the literature, especially with regard to the association between urban living and nafld. however, i wanted to put pen to paper to draw your readers’ attention to a possible misinterpretation of the association between marriage and nafld. while the authors have tried to adjust for the effects of well-recognized risk factors for nafld in multivariate logistic regression, it has not been properly performed. to the best of our knowledge, being over 40 years of age is a significant risk factor for nafld, which is not confounded by other predictors.
