Correlation of total serum carotenoids with BV. The central red dots represent serum carotenoid concentrations, with each point contributing to a continuous fitted curve. The region between the two blue dashed lines corresponds to the 95% confidence interval. The X-axis is serum carotenoid levels (continuous variable), and the Y-axis is odds ratios (ORs). ORs were computed from Model II in a multivariate logistic regression analysis
