Correlation between RBC folate and T. vaginalis infection. The natural spline curve indicates the linear association between RBC folate and the T. vaginalis infection ratio (Plinearity = 0.0007). The area between the dotted blue lines is regarded as a 95% confidential interval. Each red point reveals the concentration of RBC folate, forming a continuous fitting curve. Ratios are based on model II in multivariate logistic regression models, with all confounders (age, PIR, BMI, race, dietary calcium intake, serum or plasma cholesterol, education status, alcohol consumption and marital status) adjusted
