Role of Diet and Nutritional Supplements in Parkinson’s Disease Progression
Table 4
Logistic regression model of dietary behaviors and PD progression. Predicted PD severity score, as measured by the PRO-PD. Participants were asked to select all of the statements that were true over the prior 6 months; plastic bottle utilization was evaluated on a 10-point scale, also over the prior 6 months. Adjusted for years since diagnosis, age, and gender. Adjusted for years since diagnosis, age, gender, and income.
