Estimates from principal component regression.
(a) Scree plot shows the eigenvalue of each component. Components with an eigenvalue ≥1 were extracted. (b) Component matrix shows the correlation between z-scores of the original variables and principal components. Color signifies the direction and color depth quantifies the size, as indicated in the scale bar. (c) and (d) Effect size on SBP / DBP (mmHg) per one standard deviation (SD) change in variables, calculated according to the regression equations and component matrix (e.g. SBP and DBP decreased by 2 mmHg and 1 mmHg, respectively, per one SD increase in serum folate [nmol/L], after adjustment for all other variables).
