Schematic representation of the “multimodal” approach in which minimal models of glucose-insulin regulation (e.g., Bergman [118]) and cardiovascular autonomic control (e.g., Blasi et al. [138]) can be employed along with measures derived from polysomnography and dual-energy Xray absorptiometry to establish functional relationships that link autonomic and metabolic function with obesity and severity of sleep-disordered breathing.
