Heat map for 2-, 3- and 4-component solutions. These maps are grouped by pattern for ease of interpretation. For each extracted component, the cohort was sorted by ICA scores and split into two equal subsamples by the median; thus, the two bars for a given component represents the lowest and highest ICA scores, labeled low risk and high risk in the figure. For each median group, the average scores for each of the 20 variables are provided. High risk means for the individual variables (e.g. higher BP values) are depicted as red and low risk means are shown in green. Brightness of color denotes more extreme (high or low) scores
