Figure 2.

Distribution of HFz and PEPz scores across the CHASRS population, and relation to the derived CAR and CAB metrics. The overall distribution deviates considerably from the reciprocal diagonal representing a bipolar model. Individuals in the Reciprocal Parasympathetic quadrant would have relatively high CAB scores, whereas those in the Reciprocal Sympathetic quadrant would have relatively low CAB scores. An additional dimension is reflected along the coactivity diagonal. Individuals in the Coactivation quadrant would have relatively high CAR scores, whereas those in the Coinhibition quadrant would have relatively low CAR scores.
