Multivariable logistic regression models and trend analyses were employed to examine the relationship between average dietary fiber intake (ADFI, g\/day) and PD prevalence. Additionally, restricted cubic spline (RCS) models were used to investigate the potential nonlinear dose\u2013response relationship between ADFI and PD.
