Abstract

In a study of 8,024 adults, 2,634 were found to have (CircS).

  • (BRI) is positively associated with the prevalence of CircS.
  • The odds of having CircS increase by a factor of 2.821 for higher BRI levels.
  • Categorizing BRI into quartiles shows that higher BRI correlates with higher CircS prevalence compared to the lowest quartile.
  • A threshold value of BRI at 5.91 indicates significant increases in CircS prevalence with increases in BRI.
  • Each one-unit increase in BRI below the threshold elevates the prevalence of CircS by a factor of 2.681.
  • Subgroup analyses suggest the positive association between BRI and CircS is consistent across different populations.
