Fig. 3. Effects of colon-delivered SCFAs on cortisol awakening response.

Fig. 3

Cortisol awakening response (CAR) before and after colonic delivery of placebo, low SCFA dose, and high SCFA dose. CAR was not modulated by colonic SCFA administration. T + 00 represents time upon waking. Graphs show means of transformed cortisol (transformed_cortisol = ((cortisol + 1)**−0.5 − 1)/−0.5) concentrations ± SE.
