(A) Absolute beta 2 power chart and corresponding (B) topograms according to design in the 5-min exposure.
Absolute beta 2 power in all ROIs except ROI-1, the control design was significantly higher than that of the greening design. Error bars are expressed as standard deviation. Asterisks above the bars indicate statistically significant between-design differences (*: p < 0.05; **: p < 0.01). ROI, Region of interest; Control, control design; Japanese, Japanese design; Tropical, tropical design.
