Univariable analysis showed that fruit, dairy products, vegetables, and water, but not fried foods, fermented foods, spicy foods, and eggs, were preventive factors against RAS. After adjusting for age and sex, multivariable regression analysis suggested that fruit (adjusted odds ratio [aOR]\u2009=\u20090.430, 95% confidence interval [CI]\u2009=\u20090.218\u20130.847) and water (aOR\u2009=\u20090.294, 95% CI\u2009=\u20090.119\u20130.726) were protective factors against RAS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study found that the consumption of fruit and water was negatively associated with RAS.
