Changes in DASH scores predicted by changes in serum proteins from baseline to 3 mo in the PLS analyses. Two factors were extracted in the PLS analyses, explaining 35.7% of the variation in the dependent variable (i.e., change in the DASH score from 0 to 3 mo) and 57.2% of the variation in the predictors (changes in serum proteins) (n = 47). The graphs show correlation between the response scores (change in DASH score from 0 to 3 mo) and the predictor scores (changes in serum proteins from 0 to 3 mo) for the 2 extracted factors. Each number represents a participant. The color bar indicates changes in DASH score from negative (blue) to positive (red). DASH, Dietary Approaches to Stop Hypertension; PLS, partial least squares.
