FIGURE 5

Variable importance plot (A) and regression parameter profile (B) from PLS analysis (n = 34 for 2 mo; n = 26 for 6 mo). This graph shows the variable important plot (A) and regression parameter profile (B), where in A, several predictors (dietary markers) met or exceeded the Variable Importance for Projection (VIP) statistic Wold of 0.8. The VIP statistic of Wold illustrates the contribution of each predictor in fitting the PLS model for both predictors and clinical outcomes. The most important dietary markers for changes at 6 mo were monounsaturated fat, soluble fiber, and animal protein. Changes at 2 mo had similar important dietary markers. The regression parameter profile shows absolute coefficients for the centered and scaled parameter estimates (B). GAD-7, Generalized Anxiety Disorder 7-Item Scale; PLS, partial least squares analysis; SCL-20, Depression Symptom Checklist-20.
