Fig. 6From: Gender differences in the psychophysiological effects induced by VOCs emitted from Japanese cedar (Cryptomeria japonica)Variation of salivary sIgA levels changes at a pre-, b during, and c post-experiment measurements. The bar in a–c show the changes in the salivary cortisol levels of participants in the control condition (left) and Japanese cedar wood panels (experimental; light) conditions: male participants (white) and female participants (black).CNT indicates the control condition, while WOOD indicates the experimental condition. The bars in a show that the differences between conditions were not significant. The bars in b show that the differences between conditions were not significant. The bars in c show that the difference in values between male and female participants was significant (p = 0.029) in the Japanese cedar wood panels condition. *statistical significance (p < 0.05).
