Using Graph Theory to Assess the Interaction between Cerebral Function, Brain Hemodynamics, and Systemic Variables in Premature Infants

Figure 8

The relation between features and ∆, computed from the MABP-EEG interaction curves presented in Figure 6, and PMA and propofol. The data points and the linear least squares fit are depicted in black and gray, respectively. The shaded area indicates the 95-percentage confidence bounds on the least squares fit. The coefficient of (partial) determination is indicated in each plot (subscripts A and D denote PMA and propofol dose, resp.). A single asterisk, double asterisks, and triple asterisks denote a value smaller than 0.05, 0.01, and 0.001, respectively.
